The HIN202E - HIN232E family of RS-232
transmitters/receivers interface circuits meet all ElA highspeed RS-232E and V.28 specifications, and are particularly
suited for those applications where ±12V is not available. A
redesigned transmitter circuit improves data rate and slew
rate, which makes this suitable for ISDN and high speed
modems. The transmitter outputs and receiver inputs are
protected to ±15kV ESD (Electrostatic Discharge). They
require a single +5V power supply and feature onboard
charge pump voltage converters which generate +10V and
-10V supplies from the 5V supply. The family of devices
offers a wide variety of high-speed RS-232
transmitter/receiver combinations to accommodate various
applications (see Selection Table).
The HIN206E, HIN211E and HIN213E feature a low power
shutdown mode to conserve energy in battery powered
applications. In addition, the HIN213E provides two active
receivers in shutdown mode allowing for easy “wakeup”
capability.
The drivers feature true TTL/CMOS input compatibility, slew
rate-limited output, and 300Ω power-off source impedance.
The receivers can handle up to ±30V input, and have a 3kΩ
to 7kΩ input impedance. The receivers also feature
hysteresis to greatly improve noise rejection.

Detailed Description
The HIN2XXE family of high-speed RS-232
transmitters/receivers are powered by a single +5V power
supply, feature low power consumption, and meet all ElA
RS232C and V.28 specifications. The circuit is divided into
three sections: the charge pump, transmitter, and receiver.
Charge Pump
An equivalent circuit of the charge pump is illustrated in
Figure 3. The charge pump contains two sections: the
voltage doubler and the voltage inverter. Each section is
driven by a two phase, internally generated clock to
generate +10V and -10V. The nominal clock frequency is
125kHz. During phase one of the clock, capacitor C1 is
charged to V
added to V
V
. During phase two, C2 is also charged to 2VCC, and
CC
then during phase one, it is inverted with respect to ground
to produce a signal across C4 equal to -2V
pump accepts input voltages up to 5.5V. The output
. During phase two, the voltage on C1 is
CC
, producing a signal across C3 equal to twice
CC
. The charge
CC
impedance of the voltage doubler section (V+) is
approximately 200Ω, and the output impedance of the
voltage inverter section (V-) is approximately 450Ω. A typical
application uses 0.1µF capacitors for C1-C4, however, the
value is not critical. Increasing the values of C1 and C2 will
lower the output impedance of the voltage doubler and
inverter, increasing the values of the reservoir capacitors, C3
and C4, lowers the ripple on the V+ and V- supplies.
During shutdown mode (HIN206E, HIN211E and HIN213E)
the charge pump is turned off, V+ is pulled down to V
CC
, V-
is pulled up to GND, and the supply current is reduced to
less than 10µA. The transmitter outputs are disabled and the
receiver outputs (except for HIN213E, R4 and R5) are
placed in the high impedance state.
Transmitters
The transmitters are TTL/CMOS compatible inverters which
translate the inputs to RS-232 outputs. The input logic
threshold is about 26% of V
1 at the input results in a voltage of between -5V and V- at
the output, and a logic 0 results in a voltage between +5V
and (V+ -0.6V). Each transmitter input has an internal 400kΩ
pullup resistor so any unused input can be left unconnected
and its output remains in its low state. The output voltage
swing meets the RS-232C specifications of ±5V minimum
with the worst case conditions of: all transmitters driving 3kΩ
minimum load impedance, V
= 4.5V, and maximum
CC
allowable operating temperature. The transmitters have an
internally limited output slew rate which is less than 30V/µs.
The outputs are short circuit protected and can be shorted to
ground indefinitely. The powered down output impedance is
a minimum of 300Ω with ±2V applied to the outputs and
V
= 0V.
CC
Receivers
The receiver inputs accept up to ±30V while presenting the
required 3kΩ to 7kΩ input impedance even if the power is off
(V
= 0V). The receivers have a typical input threshold of
CC
1.3V which is within the ±3V limits, known as the transition
region, of the RS-232 specifications. The receiver output is
0V to V
greater than 2.4V and high whenever the input is floating or
driven between +0.8V and -30V. The receivers feature 0.5V
hysteresis (except during shutdown) to improve noise
rejection. The receiver Enable line EN
when unasserted, disables the receiver outputs, placing
them in the high impedance mode. The receiver outputs are
also placed in the high impedance state when in shutdown
mode (except HIN213E R4 and R5).

HIN213E Operation in Shutdown
The HIN213E features two receivers, R4 and R5, which
remain active in shutdown mode. During normal operation
the receivers propagation delay is typically 0.5µs. This
propagation delay may increase slightly during shutdown.
When entering shut down mode, receivers R4 and R5 are
not valid for 80µs after SD
= VIL. When exiting shutdown
mode, all receiver outputs will be invalid until the charge
pump circuitry reaches normal operating voltage. This is
typically less than 2ms when using 0.1µF capacitors.
Application Information
The HIN2XXE may be used for all RS-232 data terminal and
communication links. It is particularly useful in applications
where ±12V power supplies are not available for
conventional RS-232 interface circuits. The applications
presented represent typical interface configurations.
A simple duplex RS-232 port with CTS/RTS handshaking is
illustrated in Figure 7. Fixed output signals such as DTR
(data terminal ready) and DSRS (data signaling rate select)
is generated by driving them through a 5kΩ resistor
connected to V+.
In applications requiring four RS-232 inputs and outputs
(Figure 8), note that each circuit requires two charge pump
capacitors (C1 and C2) but can share common reservoir
capacitors (C3 and C4). The benefit of sharing common
reservoir capacitors is the elimination of two capacitors and
the reduction of the charge pump source impedance which
effectively increases the output swing of the transmitters.
