DS7837 Datasheet | National Semiconductor

Description The DS7837 DS8837 are high speed receivers designed for use in bus organized data transmission systems interconnected by terminated 120X impedance lines The external termination is intended to be 180X resistor from the bus to the a 5V logic supply together with a 390X resistor from the bus to ground The receiver design employs a built-in input hysteresis providing substantial noise immunity Low input current allows up to 27 driver receiver pairs to utilize a mon bus Disable inputs provide time discrimination Disable inputs and receiver outputs are TTL patible Performance is optimized for systems with bus rise and fall times s 1 0 ms V Features Y Y Y Y Y Low receiver input current for normal VCC or VCC e 0V (15 m A typ) Six separate receivers per package Built-in receiver input hysteresis (1V typ) High receiver noise immunity (2V typ) Temperature insensitive receiver input thresholds track bus logic levels TTL patible disable and output Molded or cavity dual-in-line or flat package High speed Typical Application TL F 5811 - 1 Connection Diagram Dual-In-Line Package TL F 5811 - 2 Top View Order Number DS7837J DS8837M or DS8837N See NS Package Number J16A M16A or N16A C1996 National Semiconductor Corporation TL F 5811 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 Operating Temperature Range DS7837 DS8837 7V 5 5V b 55 C to a 125 C 0 C to a 70 C Operating Conditions Min Supply Voltage (VCC) DS7837 DS8837 Temperature (TA) DS7837 DS8837 45 4 75 b 55 Max 55 5 25 a 125 a 70 Units V V C C 0 b 65 C to a 150 C Storage Temperature Range Maximum Power Dissipation at 25 C Cavity Package 1433 m W Molded DIP Package 1362 m W SO Package 1002 m W Lead Temperature (Soldering 4 seconds) 260 C Derate cavity package 9 6 m W C above 25 C...
