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
