16-Bit Registered Transceiver with 3-STATE Outputs
General Description
The ABT16543 16-bit transceiver contains two sets of D-
type latches for temporary storage of data flowing in either
direction. Separate Latch Enable and Output Enable inputs
are provided for each register to permit independent con-
trol of inputting and outputting in either direction of data
flow. Each byte has separate control inputs, which can be
shorted together for full 16-bit operation.
Ordering Code:
Devices also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
