MULTIPLE RS-232 DRIVERS AND RECEIVERS AZ75232

General Description

The AZ75232 combines three drivers and five receiv­ers, which conform to the EIA/TIA-232-F and ITU
v.28 standards. Each receiver converts EIA/TIA-232-F
inputs to 5-V TTL/CMOS levels and each driver con­verts TTL/CMOS input levels into EIA/TIA-232-F
levels.

The flow-through pinout facilitates simple non-cross­over board layout. The AZ75232 provides a one-chip
solution for the common 9-pin serial RS-232 interface
between data terminal and data communications equip­ment.

The AZ75232 is available in SOIC-20, SSOP-20 and
TSSOP-20 packages.

Features

· Single Chip with Easy Interface between UART

and Serial-Port Connector

· Meet the Requirement of EIA/TIA-232-F and

ITU v.28 Standards

· Designed to Support Data Rates up to 120kbit/s

· 3 Drivers and 5 Receivers

· Flow-through Pinout

Applications

· Mother Board

· Peripheral Equipment
