FK PACKAGE (TOP VIEW) description The SN55115 and SN75115 dual differential line receivers are designed to sense small differential signals in the presence of large mon-mode noise. These devices give TTL-patible output signals as a function of the differential input voltage. The open-collector output configuration permits the wire-ANDing of similar TTL outputs (such as SN5401/SN7401) or other SN55115/SN75115 line receivers. This permits a level of logic to be implemented without extra delay. 1STRB 1RTC NC 1B 1RT 3 2 1 20 19 9 10 11 12 13 2YP 2STRB NC 2RTC 2B 1A GND NC 2A 2RT - No internal connection The output stages are similar to TTL totem-pole outputs, but with sink outputs, 1YS and 2YS, and the corresponding active pullup terminals, 1YP and 2YP, available on adjacent package pins. The frequency response and noise immunity may be provided by a single external capacitor. A strobe input is provided for each channel. With the strobe in the low level, the receiver is disabled and the outputs are forced to a high...
