SEMICONDUCTOR TECHNICAL DATA
Low-Voltage CMOS
Octal D-Type Flip-Flop
With 5V-Tolerant Inputs and Outputs
(3-State, Non-Inverting)
The MC74LCX374 is a high performance, nonâinverting octal Dâtype
flipâflop operating from a 2.7 to 3.6V supply. High impedance TTL
compatible inputs significantly reduce current loading to input drivers
while TTL compatible outputs offer improved switching noise
performance. A VI specification of 5.5V allows MC74LCX374 inputs to be
safely driven from 5V devices.
The MC74LCX374 consists of 8 edgeâtriggered flipâflops with
individual Dâtype inputs and 3âstate true outputs. The buffered clock and
buffered Output Enable (OE) are common to all flipâflops. The eight
flipâflops will store the state of individual D inputs that meet the setup and
hold time requirements on the LOWâtoâHIGH Clock (CP) transition. With
the OE LOW, the contents of the eight flipâflops 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 flipâflops.
