BCD AZ75232G-G1 Multiple rs-232 drivers and receiver Datasheet

Data Sheet
MULTIPLE RS-232 DRIVERS AND RECEIVERS
AZ75232
General Description
Features
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.
Applications
·
·
The AZ75232 is available in SOIC-20, SSOP-20 and
TSSOP-20 packages.
