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 common-mode noise. These devices give TTL-compatible 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 4 18 5 17 6 16 7 15 8 14 9 10 11 12 13 2YP 2STRB NC 2RTC 2B 1A GND NC 2A 2RT NC – No internal connection The output stages are similar to TTL totem-pole outputs, but with sink outputs...
