SN74ABT16543 具有三态输出的 16 位寄存收发器
SN74ABT16543 描述
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. If is low and is low, the A-to-B latches are transparent; a subsequent low-to-high transition of puts the A latches in the storage mode. With and both low, the 3-state B outputs are active and reflect the data present at the output of the A latches.
