A separate response control 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 SN89 and SN89A are characterized for operation over the full military temperature range of C to C. The MC89, MC89A, SN789, and SN789A are characterized for operation from C to 7 C. logic symbol SN89, SN89A...J OR W PACKAGE MC89, MC89A, SN789, SN789A D, N, OR NS PACKAGE (TOP VIEW) A CONT Y A CONT Y GND logic diagram (positive logic) V CC A CONT Y A CONT Y The NS package is only available left-end taped and reeled.
