Overview

DM74AS640 3-STATE Octal Bus Transceiver October 1986 Revised March 2000 DM74AS640 3-STATE Octal Bus Transceiver General Description This advanced Schottky device contains 8 pairs of 3STATE logic elements configured as octal bus transceiver.
This circuit is designed for use in memory, microprocessor systems and in asynchronous bidirectional data buses.
This device transmits data from the A bus to the B bus, or vice versa, depending upon the logic level of the direction control input (DIR).
The enable input (G) can be used to disable the devices, effecting isolation of buses A and B.
The 3-STATE circuitry also contains a protection feature that prevents these transceivers from glitching the ...
