HD74ALVCH16245
16-bit Bus Transceivers with 3-state Outputs
ADE-205-134C (Z)
4th. Edition
December 1999
Description
The HD74ALVCH16245 is designed for asynchronous communication between data buses. The control
function implementation minimizes external timing requirements. This device can be used as two 8-bit
transceivers or one 16-bit transceiver. It allow data transmission from the A bus to the B bus or from the B
bus to the A bus depending upon the logic level at the direction control (DIR) input. The output enable
(
OE
) input can be used to disable the device so that the buses are effectively isolated. Active bus hold
circuitry is provided to hold unused or floating data inputs at a valid logic level.
