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. SOIC-20 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 Mother Board Peripheral Equipment SSOP-20 TSSOP-20 Figure 1.
