GENERAL DESCRIPTION
The ADM222, ADM232A, ADM242 are a family of high speed
RS-232 line drivers/receivers offering transmission rates up to
200 kB/s. Operating from a single +5 V power supply, a highly
efficient on-chip charge pump using small (0.1 µF) external
capacitors allows RS-232 bipolar levels to be developed. Two
RS-232 drivers and two RS-232 receivers are provided on each
device.
The devices are fabricated on BiCMOS, an advanced mixed
technology process which combines low power CMOS with high
speed bipolar circuitry. This allows for transmission rates up to
200 kB/s yet minimizes the quiescent power supply current to
under 5 mA.
The ADM232A is a pin-compatible, high speed upgrade for the
AD232 and for the ADM232L. It is available in 16-pin DIP and
in both narrow and wide surface mount (SOIC) packages.
The ADM222 contains an additional shutdown (
tion which may be used to disable the device thereby reducing
the supply current to 0.1 µA. During shutdown, all transmit/
receive functions are disabled. The ADM222 is available in
18-pin DIP and in a wide surface mount (SOIC) package.
The ADM242 combines both shutdown (
EN) functions. The shutdown function reduces the supply
(
curent to 0.1 mA. During shutdown, the transmitters are
disabled but the receivers continue to operate normally. The
enable function allows the receiver outputs to be disabled
thereby facilitating sharing a common bus. The ADM242 is
available in 18-pin DIP and in a wide surface mount (SOIC)
package.

ADM222/ADM232A/ADM242
GENERAL INFORMATION
The ADM222/ADM232A/ADM242 are high speed RS-232
drivers/receivers requiring a single digital +5 V supply. The RS232 standard requires transmitters that will deliver ± 5 V
minimum on the transmission channel and receivers that can
accept signal levels down to ±3 V. The parts achieve this by
integrating step up voltage converters and level shifting transmitters and receivers onto the same chip. CMOS technology is
used to keep the power dissipation to an absolute minimum.
All devices contains an internal charge pump voltage doubler
and a voltage inverter that generates ± 10 V from the +5 V
input. Four external 0.1 µF capacitors are required for the
internal charge pump voltage converter.
The ADM222/ADM232A/ADM242 is a modification, enhancement and improvement to the AD230-AD241 family and
derivatives thereof. It is essentially plug-in compatible and does
not have materially different applications.
CIRCUIT DESCRIPTION
The internal circuitry consists of four main sections. These are:
A Charge Pump Voltage Converter
TTL/CMOS to RS-232 Transmitters
RS-232 to TTL/CMOS Receivers
Enable and Shutdown Functions.
Charge Pump DC-DC Voltage Converter
The Charge Pump Voltage converter consists of an oscillator
and a switching matrix. The converter generates a ± 10 V supply
from the input 5 V level. This is done in two stages using a
switched capacitor technique. The 5 V input supply is doubled
to 10 V using capacitor C1 as the charge storage element. The
–10 V level is also generated from the input 5 V supply using C1
and C2 as the storage elements.
Capacitors C3 and C4 are used to reduce the output ripple.
Their values are not critical and can be reduced if higher levels
of ripple are acceptable. The charge pump capacitors C1 and
C2 may also be reduced at the expense of higher output
impedance on the V+ and V– supplies.
The V+ and V– supplies may also be used to power external
circuitry if the current requirements are small. Please refer to
the typical performance characteristics which shows the V+, V–
output voltage vs. current.
In the shutdown mode the charge pump is disabled and V+
decays to V
Transmitter (Driver) Section
while V– decays to 0 V.
CC
The Drivers convert TTL/CMOS input levels into RS-232
output levels. With V
= +5 V and driving a typical RS-232
CC
load, the output voltage swing is ±9 V. Even under worst case
conditions the drivers are guaranteed to meet the ± 5 V RS-232
minimum requirement.
The input threshold levels are both TTL and CMOS compatible with the switching threshold set at V
= 5 V the switching threshold is 1.25 V typical. Unused
V
CC
/4. With a nominal
CC
inputs may be left unconnected, as an internal 400 kΩ pull- up
resistor pulls them high forcing the outputs into a low state.
As required by the RS-232 standard, the slew rate is limited to
less than 30 V/µs without the need for an external slew limiting
capacitor, and the output impedance in the power-off state is
greater than 300 Ω.
Receiver Section
The receivers are inverting level shifters which accept RS-232
input levels (±3 V to ±15 V) and translate them into 5 V TTL/
CMOS levels. The inputs have internal 5 kΩ pull-down resistors
to ground and are also protected against overvoltages of up to
±30 V. The guaranteed switching thresholds are 0.8 V minimum and 2.4 V maximum which are well within the ±3 V RS232 requirement. The low level threshold is deliberately positive
as it ensures that an unconnected input will be interpreted as a
low level.
The receivers have Schmitt trigger input with a hysteresis level
of 0.5 V. This ensures error free-reception for both noisy inputs
and for inputs with slow transition times
Enable and Shutdown Functions
On the ADM222, both receivers are fully disabled during
shutdown.
On the ADM242, both receivers continue to operate normally.
This function is useful for monitoring activity so that when it
occurs, the device can be taken out of the shutdown mode.
The ADM242 also contains a receiver enable function (EN)
which can be used to fully disable the receivers, independent of
SHDN.
