Description
General part information
SN74LVT16543 Series
The 'LVT16543 are 16-bit registered transceivers designed for low-voltage (3.3-V) VCCoperation, 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 (or) and output-enable (or) inputs are provided for each register to permit independent control in either direction of data flow.
The A-to-B enable () input must be low in order to enter data from A or to output data from B. Ifis low andis low, the A-to-B latches are transparent; a subsequent low-to-high transition ofputs the A latches in the storage mode. Withandboth 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,, andinputs.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
