Description
General part information
74ABT16543 Series
The 'ABT16543 16-bit registered transceivers contain two sets of D-type latches for temporary storage of data flowing in either direction. The 'ABT16543 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 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.
To ensure the high-impedance state during power up or power down,should be tied to VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
