FK PACKAGE (TOP VIEW) 1ZS 1ZP NC VCC 2ZP description The SN55114 and SN75114 dual differential line drivers are designed to provide differential output signals with the high-current capability for driving balanced lines, such as twisted pair, at normal line impedances without high power dissipation. The output stages are similar to TTL totem-pole outputs, but with the sink outputs, YS and ZS, and the corresponding active pullup terminals, YP and ZP, available on adjacent package pins. Since the output stages provide TTL-compatible output levels, these devices can also be used as TTL expanders or phase splitters. 1YS 1YP NC 1A 1B 3 2 1 20 19 4 18 5 17 6 16 7 15 8 14 9 10 11 12 13 2ZS 2YS NC 2YP 2C 1C GND NC 2A 2B NC – No internal connection The SN55114 is characterized for...
