FK PACKAGE (TOP VIEW) description The SN55182 and SN75182 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 polarity of the differential input voltage. The frequency response of each channel can be easily controlled by a single external capacitor to provide immunity to differential noise spikes. The output goes to a high level when the inputs are open circuited. A strobe input (STRB) is provided that, when in the low level, disables the receiver and forces the output to a high level. 1IN+ NC 1STRB NC 1RTC 3 2 1 20 19 4 18 5 17 6 16 7 15 8 14 9 10 11 12 13 2RT NC 2IN+ NC 2STRB 1OUT GND NC 2OUT 2RTC NC – ...
