description  
TheSN75C189andSN75C189Aarelow-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 to TIA/EIA-232-F.  
The SN75C189 has a 0.33-V typical hysteresis, compared with 0.97 V for the 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 is in the high logic state  
if the input is open circuit or shorted to ground.  
These devices have an on-chip filter that rejects input pulses of less than 1-µs duration. An external capacitor  
can be connected from the control pins to ground to provide further input noise filtering for each receiver.  
The SN75C189 and SN75C189A have been designed using low-power techniques in a bipolar technology. In  
most applications, these receivers interface to single inputs of peripheral devices such as UARTs, ACEs, or  
microprocessors. By using sampling, such peripheral devices usually are insensitive to the transition times of  
theinputsignals. Ifthisisnotthecase, orforotheruses, itisrecommendedthattheSN75C189andSN75C189A  
outputs be buffered by single Schmitt input gates or single gates of the HCMOS, ALS, or 74F logic families.  
The SN75C189 and SN75C189A are characterized for operation from 0°C to 70°C.
