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

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.
