HD74ALVCH16543 Datasheet (Hitachi Semiconductor) - 16-bit Registered Transceivers with 3-state Outputs

HD74ALVCH16543, 16-bit Registered Transceivers with 3-state Outputs

The HD74ALVCH16543 can be used as two 8-bit transceivers or one 16-bit transceiver.

Separate latch enable (LEAB or LEBA ) and output enable (OEAB or OEBA ) inputs are provided for each register to permit independent control in either direction of data flow.

The A to B enable (CEAB) input must be low
