DM8820
DM8820 is dual line receiver manufactured by National Semiconductor.
description
The DM7820, specified from
- 55°e to 125°e, and the DM8820, specified from o Oe to 70oe, are digital line receivers with two pletely 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 mon mode signals while responding to small differential signals. The output is directly patible 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....
