DESCRIPTION
The 74ALVCH16623 is a high-performance, low-power, low-voltage, Si-gate
CMOS device, superior to most advanced CMOS compatible TTL families.
The 74ALVCH16623 is a 16-bit transceiver featuring non-inverting 3-state bus
compatible outputs in both send and receive directions.
This 16-bit bus transceiver is designed for asynchronous two-way
communication between data buses. The control function implementation
allows maximum flexibility in timing. This device allows data transmission from
the A bus to the B bus or from the B bus to the A bus, depending upon the logic
levels at the enable inputs (nOE
AB
, nOE
BA
). The enable inputs can be used to
disable the device so that the buses are effectively isolated. The dual enable
function configuration gives this transceiver the capability to store data by
simultaneous enabling of nOE
AB
and nOE
BA
. Each output reinforces its input in
this transceiver configuration. Thus, when all control inputs are enabled and all
other data sources to the four sets of the bus lines are at high-impedance
OFF-state, all sets of bus lines will remain at their last states. The 8-bit codes
appearing on the two double sets of buses will be complementary. This device
can be used as two 8-bit transceivers or one 16-bit transceiver.
To ensure the high-impedance state during power-on or power-down, OE

through a pull-down resistor; the minimum value of the resistor is determined
by the current-sinking/current-sourcing capability of the driver.
Active bus hold circuitry is provided to hold unused or floating data inputs at a
valid logic level.
