General Description
This advanced Schottky device contains 8 pairs of 3-STATE 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 bus during power-up or power-down.
