The SN74LVTH32374 is a 32-bit edge-triggered D-type flip-flop 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. This device is particularly suitable
for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
