DESCRIPTION
The 74LVT32374 is a high-performance BICMOS product
designed for VCC operation at 3.3 V.
The 74LVT32374 is a 32-bit edge-triggered D-type flip-flop
featuring non-inverting 3-state outputs. The device can be
used as four 8-bit flip-flops, or two 16-bit flip-flops or one
32-bit flip-flop. On the positive transition of the clock (CP),
the Q outputs of the flip-flop take on the logic levels set-up
at the D inputs.
