DESCRIPTION
The 74LVC623A is a high performance, low-power, low-voltage
Si-gate CMOS device, superior to most advanced CMOS
compatible TTL families.
The 74LVC623A is an octal transceiver featuring non-inverting
3-State bus compatible outputs in both send and receive directions.
This octal 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 levels at the
enable inputs (OEAB, OEBA). 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 OEAB and
OEBA. Each output reinforces its input in this transceiver
configuration. Thus, when both control inputs are enabled and all
other data sources to the two sets of the bus lines are at high
impedance OFF-state, both sets of bus lines will remain at their last
states. The 8-bit codes appearing on the two sets of buses will be
identical.
The ‘623A’ is identical to the ‘620A’ but has true (non-inverting)
outputs.
