Data Sheet MULTIPLE RS-232 DRIVERS AND RECEIVERS AZ75232 General Description Features The AZ75232 combines three drivers and five receiv- Single Chip with Easy Interface between UART ers, which conform to the EIA/TIA-232-F and ITU and Serial-Port Connector v.28 standards. Each receiver converts EIA/TIA-232-F Meet the Requirement of EIA/TIA-232-F and inputs to 5-V TTL/CMOS levels and each driver con- ITU v.28 Standards verts TTL/CMOS input levels into EIA/TIA-232-F Designed to Support Data Rates up to 120kbit/s levels. 3 Drivers and 5 Receivers Flow-through Pinout The flow-through pinout facilitates simple non-cross- over board layout. The AZ75232 provides a one-chip Applications solution for the common 9-pin serial RS-232 interface between data terminal and data communications equip- ment. Mother Board Peripheral Equipment The AZ75232 is available in SOIC-20, SSOP-20 and TSSOP-20 packages. SOIC-20 SSOP-20 TSSOP-20 Figure 1.
