Functional Description
The LVT32374 and LVTH32374 consist of thirty-two edge-triggered flip-flops with individual D-type inputs and 3-STATE true
outputs. The device is byte controlled with each byte functioning identically, but independent of the other. The control pins
can be shorted together to obtain full 32-bit operation. Each byte has a buffered clock and buffered Output Enable common
to all flip-flops within that byte. The description which follows applies to each byte. Each flip-flop will store the state of their
individual D-type inputs that meet the setup and hold time requirements on the LOW-to-HIGH Clock (CPn) transition. With
the Output Enable (OEn) LOW, the contents of the flip-flops are available at the outputs. When OEn is HIGH, the outputs go
to the high impedance state. Operation of the OEn input does not affect the state of the flip-flops.
