DS8640 Datasheet Quad Nor Unified Bus Receiver

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: DS7640 DS8640 Quad NOR Unified Bus Receiver February 1996 DS7640 DS8640 Quad NOR Unified Bus Receiver.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The DS7640 and DS8640 are quad 2-input 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 a5V logic supply together with a 390X resistor from the bus to ground The design employs a built-in input threshold providing substantial noise immunity Low input current allows up to 27 driver receiver pairs to utilize a mon bus

Key Features
