DM7837
DM7837 is hex unified bus receiver manufactured by National Semiconductor.
description
The DM7837/DM8837 are high speed receivers designed for use in bus organized data transmission systems Interconnected by terminated 120n Impedance lines. The external termination is intended to be 180[2 re SIStor from the bus to the +5V logic supply together with a 390[2 resistor from the bus to ground. The receiver design employs a built-in Input hysteres Is providing substantial n Oise Immunity. Low input current allows up to 27 driver/receiver pairs to utilize a mon bus. Disable Inputs provide time discriminat IOn. Disable Inputs and receiver outputs are DTL/TTL patible. Performance is optimized for systems with bus r ISe and fall times::::: l Oll S. features

Vee = OV (1511A typ)
- Six separate receivers per package
- Built-in receiver input hysteresis (l V typ)
- High receiver n Oise immunity (2V typ)
- Temperature insensitive receiver Input...
