Overview
HD74ALVCH162543 16-bit Registered Transceivers with 3-state Outputs ADE-205-183 (Z) Preliminary 1st.
Edition December 1996 Description The HD74ALVCH162543 can be used as two 8-bit transceivers or one 16-bit transceiver.
Separate latch enable (LEAB or LEBA) and output enable ( OEAB or OEBA ) inputs are provided for each register to permit independent control in either direction of data flow.
The A to B enable (CEAB) input must be low in order to enter data from A or to output data from B.
If CEAB is low and LEAB is low, the A to B latches are transparent; a subsequent low to high transition of LEAB puts the A latches in the storage mode.
With CEAB and OEAB both low, the 3-state B outputs are...
