Overview

Line 0 rivers/Receivers OM7820/0M8820 dual line receiver general description The DM7820, specified from ·55°e to 125°e, and the DM8820, specified from oOe to 70oe, are digital line receivers with two completely indepen' dent 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 RTL, DTL or TTL integrated circuits.
features • Operation from a single +5V logic supply • Input voltage range of ±15V • Each channel can be strobed independently • High input resistance • Fanout of two with either DTL or TTL integrated circuits The response time can be controlled with an ex· ternal capacitor to eliminate noise spikes, and the output state is determined for open inputs.
Ter· mination resistors for the twisted pair line are also included in the circuit.
