Dual Line Receiver - National Semiconductor

The DS7820 specified from b55Cto a125C, and the DS8820 specified from 0Cto a70C, are digital line re- ceivers 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 in- put designed to reject large common mode signals while responding to small differential signals. The output is direct- ly compatible with TTL or LS integrated circuits. The response time CAN be controlled with an external ca- pacitor to eliminate noise spikes, and the output state is determined for open inputs. Termination resistors for the twisted pair line are also included in the circuit. Both the DS7820 and the DS8820 are specified, worst case, over their full operating temperature range, for g10-percent sup- ply voltage variations and over the entire input voltage range.
