description
The ’ALVTH16374 devices are 16-bit edge-triggered D-type flip-flops with 3-state outputs designed for 2.5-V
or 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.
These devices can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the positive transition of the clock
(CLK), the flip-flops store the logic levels set up at the data (D) inputs.
