74ACT16543 具有三态输出的 16 位寄存收发器
74ACT16543 描述
The 'ACT16543 are 16-bit registered transceivers that contain two sets of D-type latches for temporary storage of data flowing in either direction. The 'ACT16543 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 (
) and inputs must be low to enter data from A or to output data to B. Having CEAB\ low and LEAB\ low makes the A-to-B latches transparent; a subsequent low-to-high transition at puts the A latches in the storage mode. Data flow from B to A is similar, but requires using the
