M5232P

The ALi's M5232P combines three drivers and five receivers from ASP trade standard AP232 bipolar quadruple drivers and receivers, respectively. The pinout matches the flow through design of the AP232 to decrease the part count, reduce the board space required, and allow easy interconnection of the UART and serial-port connector of IBM PC/AT and compatibles. The bipolar circuits and processing of the M5232P provides a rugged low-cost solution for this function at the expense of quiescent power and external passive components relative to the AP232.

The M5232P complies with the requirements of the EIA/TIA 232-D and ITU (formally CCITT) v.28 standards. These standards are for data interchange between a host computer and peripheral at signalling rates up to 20k bits/sec. The switching speeds of the M5232P are fast enough to support rates up to 120 kbps with lower capacitive loads (shorter cables). Interoperability at the higher signalling rates cannot be assured unless the designer has design control of the cable and the interface circuits at both ends. For compatibility with signalling rates to 120 kbps, use of EIA/ITA-423-B (ITU v.10) and EIA/ ITA-422-B (ITU v.11) standards are recommended.

The M5232P is operable at the temperature range of 0oC to 75.
