Preliminary Datasheet
MULTIPLE RS-232 DRIVERS AND RECEIVERS
General Description
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.

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 Max-
imum Ratings" for extended periods may affect device reliability.
