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.
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 avail-
able 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.
