MICROCIRCUIT DATA SHEET
DUAL LINE RECEIVER
General Description
The DS7820A is a improved performance digital line receiver with two completely
independent units fabricated on a single silicon chip. Intended for use with digital
systems connected by twisted pair lines, it has 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. The DS7820 is specified, worst case, over it's
full operating temperature range, for + 10-percent supply voltage variations and over the
entire input voltage range.
