1. General description
2. Features
The 74LVC623A is a high-performance, low-power, low-voltage, Si-gate CMOS device,
superior to most advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3 V or 5 V devices. In 3-state operation, outputs can
handle 5 V. These features allow the use of these devices as translators in a mixed
3.3 V or 5 V environment.
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 logic levels at the enable inputs (pins OEAB and 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 pins 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 the
bus lines will remain at their last states. The 8-bit codes appearing on the two sets of
buses will be identical.
