HD74ALVCH16543
16-bit Registered Transceivers with 3-state Outputs
ADE-205-169A (Z)
2nd. Edition
December 1999
Description
The HD74ALVCH16543 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 active and reflect the data present at the output
of the A latches. Data flow from B to A is similar but requires using
CEBA
,
LEBA
, and
OEBA
. Active
bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
