Description

The UTC75323 combines five drivers and three receivers. The flow-through design of the UTC 75323 decreases the part count, reduces the board space required, and allows easy interconnection of the UART and serial-port connector. The all-bipolar circuits and processing of the UTC 75323 provide a rugged, low-cost solution for this function.

The UTC75323 complies with the requirements of the ANSI TIA/EIA-232-Fand ITU (formerly CCITT) V.28 standards. These standards are for data interchange between a host computer and a peripheral at signal rates up to 20 Kbit/s. The switching speeds of the UTC 75323 are fast enough to support rates up to 120 kbit/s with lower capacitive loads (shorter cables). Interoperability at the higher signaling rates cannot be assured unless the designer has design control of the cable and the interface circuits at both ends. For interoperability at signaling rates up to 120 kbit/s, use of ANSI Standard TIA/EIA-423-B and TIA/EIA-422-B and ITU Recommendations V.10 and V.11 are recommended. The UTC 75323 is characterized for operation over a temperature range of 0 to 70.
