SN74LVCH16543A - Texas Instruments

SN74LVCH16543A 16-BIT REGISTERED TRANSCEIVER

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. .
