MULTIPLE RS-232 DRIVERS AND RECEIVERS
General Description
Features
Preliminary Datasheet
AZ75232
The AZ75232 combines three drivers and five receiv-
ers, 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 con-
verts TTL/CMOS input levels into EIA/TIA-232-F
levels.
The flow-through pinout facilitates simple non-cross-
over board layout. The AZ75232 provides a one-chip
solution for the common 9-pin serial RS-232 interface
between data terminal and data communications equip-
ment.
The AZ75232 is available in SOIC-20, SSOP-20 and
TSSOP-20 packages.
· 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
