SN752232,pdf(Dual RS-232 Port)

The SN752232 consists of dual ports, each containing three drivers and five receivers, which reduce board space and allow easy interconnection of the UART and two serial-port connectors of an IBM™ PC/AT™ and compatibles. The bipolar circuits and processing of this "dual GD75232" provide, a rugged, low-cost solution for this function.

The SN752232 complies with the requirements of the TIA/EIA-232-F and ITU V.28 standards. These standards are for data interchange between a host computer and a peripheral at signaling rates up to 20 kbit/s. The device supports data rates up to 120 kbit/s with lower capacitive loads (shorter cables). Interoperability at the higher signaling rates cannot be expected unless the designer has design control of the cable and the interface circuits at both ends.
