SN75C 189, and SN75C189A are low-power bipolar quadruple line receivers that are used to interface data terminal equipment (DTE) with data circuit- terminating equipment (DCE). These devices have been designed to conform with Standard ANSI/EIA-232-D-1986, which supersedes RS-232-C. The SN65C189 and SN75C 189 have a0.25 V typical hysteresis compared with 1 V for the SN65C189A and SN75C189A. Each receiver has provision for adjustment of the overall input threshold levels. This is achieved by choosing external series resistors and voltages to provide bias levels for the response control pins. The output ts in the high logic state if the input is left open circuited or shorted to grourd.

An external capacitor may be connected from the control pins to ground to provide further input noise filtering for each receiver. The SN65C189, SN75C189, SNG5C189A, and SN75C189A have been designed using low-power techniques tn a bipolar technology. In most applications, these receivers will interface to single inputs of peripheral devices such as UARTs, ACEs, or microprocessors. By using sampling, such peripheral devices are usually insensitive to the transition times of the input signals. If this is not the case, or for other uses, it is recommenaed that the SN65C 189, SN75C 189, SN65C 189A, and SN75C189A outputs be buffered by single Schmitt input gates or single gates of the HCMOS, ALS or 74F logic families. The SN65C 189 and SN65C 189A are characterized for operation from 40C to 85C. The SN75C189 and SN75C189A are characterizec for operation from OC to 70C.
