Pin Description
Functional Description
The LVT574 and LVTH574 consist of eight edge-
triggered flip-flops with individual D-type inputs and
3-STATE true outputs. The buffered clock and buffered
Output Enable are common to all flip-flops. The eight
flip-flops will store the state of their individual D-type
inputs that meet the setup and hold time requirements
on the LOW-to-HIGH Clock (CP) transition. With the Out-
put Enable (OE) LOW, the contents of the eight flip-flops
are available at the outputs. When the OE is HIGH, the
outputs go to the high impedance state. Operation of the
OE input does not affect the state of the flip-flops.
