DESCRIPTION/ORDERING INFORMATION
This 16-bit registered transceiver is designed for
1.65-V to 3.6-V VCC operation.
The SN74LVCH16543A 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.
