General Description

The ’LVTH16543 devices are 16-bit registered transceivers designed for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

These devices 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
