multiple rs-232 drivers and receivers AZ75232 preliminary datasheet 1 aug. 2006 rev. 1. 4 bcd semiconductor manufacturing limited general description the AZ75232 combines thr ee 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. 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 figure 1. package types of AZ75232 ssop-20 soic-20 tssop-20
