receivers

Datasheet - production data

Features

300 µA supply current

300 kbps minimum guaranteed data rate

6 V/µs minimum guaranteed slew rate

Meets EIA/TIA-232 specifications down

to 3 V

Available in SO16, SO16L, and TSSOP16

packages

Description

The ST3232B and ST3232C devices are 3 V

powered EIA/TIA-232 and V.28/V.24

communication interfaces with low power

requirements and high data-rate capabilities.

These devices have a proprietary low dropout

transmitter output stage providing true RS-232

performance from 3 to 5.5 V supplies. The

devices require only four small 0.1 mF standard

external capacitors for operation from a 3 V

supply.

The ST3232B and ST3232C have two receivers

and two drivers.

The devices are guaranteed to run at data rates

of 250 kbps while maintaining RS-232 output

levels. Typical applications are notebooks,

subnotebooks and palmtop computers, battery-

powered equipment, hand-held equipment,

peripherals, and printers.
