Description

The DS7820, specified from b55§C to a125§C, and the DS8820, specified from 0§C to a70§C, are 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 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 supply voltage variations and over the entire input voltage range.
