DS7820 Datasheet | National Semiconductor

Description The DS7820 specified from b55 C to a 125 C and the DS8820 specified from 0 C to a 70 C are digital line receivers with two pletely independent 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 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 Both the DS7820 and the DS8820 are specified worst case over their full operating temperature range for g 10-percent supply voltage variations and over the entire input voltage range Features Y Y Y Y Y Y Operation from a single a 5V logic supply Input voltage range of g 15V Each channel can be strobed independently High input resistance Fan out of two with TTL integrated circuits Strobe low forces output to ‘‘1’’ state Connection Diagram Dual-In-Line Package TL F 5796 - 2 Top View Order Number DS7820J or DS8820N See NS Package Number J14A or N14A For plete Military 883 Specifications See RETS Data Sheet Order Number DS7820J 883 or DS7820W 883 See NS Package Number J14A or W14B C1996 National Semiconductor Corporation TL F 5796 RRD-B30M36 Printed in U S A http national Absolute Maximum Ratings (Note 1) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage Input Voltage Differential Input Voltage Strobe Voltage Output Sink Current Storage Temperature Range Lead Temperature (Soldering 4 sec ) 8 0V g 20V g 20V Maximum Power Dissipation at 25 C Cavity Package Molded Package 1308 m W 1207 m W Derate cavity package 8 7 m W C above 25 C derate molded package 9 7 m W C above 25...
