DS7820A/DS8820A Dual Line Receiver May 1999 DS7820A/DS8820A Dual Line Receiver General Description The DS7820A and the DS8820A are improved performance digital line receivers with two completely independent units fabricated on a single silicon chip. Intended for use with digital systems connected by twisted pair lines, they have a differential input designed to reject large common mode signals while responding to small differential signals. The output is directly compatible with TTL or LS integrated circuits. The response time can be controlled with an external capacitor to reject input noise spikes. The output state is a logic “1” for both inputs open. Termination resistors for the twisted pair line are also included in the circuit.
