DESCRIPTION/ORDERING INFORMATION
The 'LVTH16373 devices are 16-bit transparent D-type latches with 3-state outputs designed for low-voltage
(3.3-V) VCC 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.
