GENERAL DESCRIPTION
The ADM3202/ADM3222/ADM1385 transceivers are high
speed, 2-channel RS-232/V.28 interface devices that operate
from a single 3.3 V power supply. Low power consumption and
a shutdown facility (ADM3222/ADM1385) make them ideal for
battery-powered portable instruments.
The ADM3202/ADM3222/ADM1385 parts conform to the
EIA-232E and CCITT V.28 specifications and operate 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 can 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 PDIP, SOIC_W, and
SOIC_N, as well as a space-saving 16-lead TSSOP. The ADM3222
is available in 18-lead PDIP and SOIC_W and in 20-lead SSOP
and TSSOP. The ADM1385 is available in a 20-lead SSOP,
which is pin-compatible with the LTC1385 CG.

ADM3202/ADM3222/ADM1385 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 ...

Page 9

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 output CC voltage swing is typically ±6 V. Receiver Section The receivers are inverting ...
