The 'LVTH162373 devices are16-bit transparent D-type latches with 3-state outputs designed for low-voltage
(3.3-V) V
CC
operation, but with the capability to provide a TTL interface to a 5-V system environment. These
devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and
working registers.
