GENERAL DESCRIPTION
The ADM3202/ADM3222/ADM1385 transceivers are high speed, 2-channel RS-232/V.28 interface devices which operate from a single +3.3 V power supply.
Low power consumption and a shutdown facility (ADM3222/ ADM1385) makes them ideal for battery powered portable instruments.
The ADM3202/ADM3222/ADM1385 conforms to the EIA­232E and CCITT V.28 specifications and operates at data rates up to 460 kbps.
Four external 0.1 µF charge pump capacitors are used for the voltage doubler/inverter permitting operation from a single +3.3 V supply.
The ADM3222 contains additional enable and shutdown cir­cuitry. The EN input may be used to three-state the receiver outputs. The SD input is used to power down the charge pump and transmitter outputs reducing the quiescent current to less than 0.5 µA. The receivers remain enabled during shutdown unless disabled using EN.
The ADM1385 contains a driver disable mode and a complete shutdown mode.
The ADM3202 is available in a 16-lead DIP, narrow and wide SOIC as well as a space saving 20-lead TSSOP package. The ADM3222 is available in 18-lead DIP, SO and in 20-lead SSOP and TSSOP. The ADM1385 is available in a 20-lead SSOP package, which is pin compatible with the LTC1385 CG.

GENERAL DESCRIPTION
The ADM3202/ADM3222/ADM1385 are RS-232 line drivers/ receivers. Step-up voltage converters coupled with level shifting transmitters and receivers allow RS-232 levels to be developed while operating from a single +3.3 V supply.
CMOS technology is used to keep the power dissipation to an absolute minimum, allowing maximum battery life in portable applications.
The ADM3202/ADM3222/ADM1385 is a modification, en­hancement and improvement to the AD230–AD241 family and its derivatives. It is essentially plug-in compatible and does not have materially different applications.
CIRCUIT DESCRIPTION
The internal circuitry consists of three main sections. These are:
1. A charge pump voltage converter
2. 3.3 V logic to EIA-232 transmitters
3. EIA-232 to 5 V logic receivers.
Charge Pump DC-DC Voltage Converter
The charge pump voltage converter consists of a 200 kHz oscil­lator and a switching matrix. The converter generates a ±6.6 V supply from the input +3.3 V level. This is done in two stages using a switched capacitor technique as illustrated below. First, the +3.3 V input supply is doubled to +6.6 V using capacitor C1 as the charge storage element. The +6.6 V level is then inverted to generate –6.6 V using C2 as the storage element. C3 is shown connected between V+ and V tive if connected between V+ and GND.
Capacitors C3 and C4 are used to reduce the output ripple. Their values are not critical and can be increased if desired. Capacitor C3 is shown connected between V+ and V also acceptable to connect this capacitor between V+ and GND.
If desired, larger capacitors (up to 10 µF) can be used for capacitors C1–C4.

Transmitter (Driver) Section
The drivers convert 3.3 V logic input levels into RS-232 output levels. With V
= +3.3 V and driving an RS-232 load, the
CC
output voltage swing is typically ±6 V.
OUTLINE DIMENSIONS
Dimensions shown in inches and (mm).
Receiver Section
The receivers are inverting level-shifters that accept RS-232 input levels and translate them into 3 V logic output levels. The inputs have internal 5 k pull-down resistors to ground and are also protected against overvoltages of up to ±30 V. Uncon­nected inputs are pulled to 0 V by the internal 5 k pull-down resistor. This, therefore, results in a Logic 1 output level for unconnected inputs or for inputs connected to GND.
The receivers have Schmitt trigger inputs with a hysteresis level of 0.4 V. This ensures error-free reception for both noisy inputs and for inputs with slow transition times.
HIGH BAUD RATE
The ADM3202E/ADM3222E feature high slew rates permitting data transmission at rates well in excess of the EIA/RS-232E specifications. RS-232 voltage levels are maintained at data rates up to 460 kbps even under worst case loading conditions. This allows for high speed data links between two terminals or indeed it is suitable for the new generation I
modem standards which
