MC74LCX374
Low−Voltage CMOS
Octal D−Type Flip−Flop
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)

MARKING
The MC74LCX374 is a high performance, non−inverting octal
D−type flip−flop operating from a 2.3 to 3.6 V supply. High
impedance TTL compatible inputs significantly reduce current
loading to input drivers while TTL compatible outputs offer improved

MC74LCX374 inputs to be safely driven from 5 V devices.
The MC74LCX374 consists of 8 edge−triggered flip−flops with
individual D−type inputs and 3−state true outputs. The buffered clock
and buffered Output Enable (OE) are common to all flip−flops. The
eight flip−flops will store the state of individual D inputs that meet the
setup and hold time requirements on the LOW−to−HIGH Clock (CP)
transition. With the 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. The OE input level does not affect the operation
of the flip−flops.
