Functional Description
The LVT16374 and LVTH16374 consist of sixteen
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 16-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.
