A separate response-control (CONT) terminal is provided for each receiver. A resistor or a resistor and bias-voltage source can be connected between this terminal and ground to shift the input threshold levels. An external capacitor can be connected between this terminal and ground to provide input noise filtering. The SN55189 and SN55189A are characterized for operation over the full military temperature range of - 55°C to 125°C. The MC1489, MC1489A, SN75189, and SN75189A are characterized for operation from 0°C to 70°C. SLLS095D - SEPTEMBER 1973 - REVISED OCTOBER 1998 SN55189, SN55189A . . .
