74LCX374 Datasheet, PDF (2/8 Pages) STMicroelectronics – OCTAL D-TYPE FLIP FLOP NON INVERTING 3-STATE WITH 5V TOLERANT INPUTS AND OUTPUTS

Functional Description
The LCX374 consists of eight edge-triggered flip-flops with
individual D-type inputs and TRI-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 re-
quirements on the LOW-to-HIGH Clock (CP) transition With
the Output 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
