Pin Description
Functional Description
The LVT374 and LVTH374 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 inputs that
meet the setup and hold time requirements on the LOW-
to-HIGH Clock (CP) transition. With the Output Enable
(OE) LOW, the contents of the eight flip-flops are avail-
able 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.
