T he 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.
T he ADM3202/ADM3222/ADM1385 conforms to the EIA-
232E and CCIT T V.28 specifications and operates at data rates
up to 460 kbps.
Four external 0.1
μ
F charge pump capacitors are used for the
voltage doubler/inverter permitting operation from a single
+3.3 V supply.
T he ADM3222 contains additional enable and shutdown cir-
cuitry. T he
EN
input may be used to three-state the receiver
outputs. T he
SD
input is used to power down the charge
pump and transmitter outputs reducing the quiescent current to
less than 0.5
μ
A. T he receivers remain enabled during shutdown
unless disabled using
EN
.
T he ADM1385 contains a driver disable mode and a complete
shutdown mode.
T he ADM3202 is available in a 16-lead DIP, narrow and wide
SOIC as well as a space saving 20-lead T SSOP package. T he
ADM3222 is available in 18-lead DIP, SO and in 20-lead SSOP
and T SSOP. T he ADM1385 is available in a 20-lead SSOP
package, which is pin compatible with the LT C1385 CG.
