DM7820
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.
Key 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. Both
