The DM7820A and the DM8820A are improved performance digital line receivers with two completely Independent units fabncated 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 .
include:
• Operation from a single +5V logic supply
• Input voltage range of ±'5V
• Strobe low forces output to "," state
• High input resjstance
• Fanout of ten with either DTL or TTL integrated circuits
• Outputs can be wire OR'ed
• Series 54174 compatible
The response time can be controlled with an ex
· ternal capacitor to reject Input noise spikes. The output state is a logic "," for both inpu.
