Description

General part information

SN74LVTH543-EP Series

These octal transceivers are designed specifically for low-voltage (3.3-V) VCCoperation, but with the capability to provide a TTL interface to a 5-V system environment.

The ’LVTH543 devices contain two sets of D-type latches for temporary storage of data flowing in either direction. 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 to enter data from A or to output data from B. If CEAB\ is low and LEAB\ is low, the A-to-B latches are transparent; a subsequent low-to-high transition of LEAB\ puts the A latches in the storage mode. With CEAB\ and OEAB\ both low, the 3-state B outputs are active and reflect the data present at the output of the A latches. Data flow from B to A is similar, but requires using the CEBA\, LEBA\, and OEBA\ inputs.
