Low-Voltage CMOS
Octal D-Type Flip-Flop
With 5V-Tolerant Inputs and Outputs
(3-State, Non-Inverting)
The MC74LCX374 is a high performance, noninverting octal Dtype
flipflop 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 edgetriggered flipflops with
individual Dtype inputs and 3state true outputs. The buffered clock and
buffered Output Enable (OE) are common to all flipflops. The eight
flipflops will store the state of individual D inputs that meet the setup and
hold time requirements on the LOWtoHIGH Clock (CP) transition. With
the OE LOW, the contents of the eight flipflops 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 flipflops.
Designed for 2.7 to 3.6V VCC Operation
5V Tolerant -- Interface Capability With 5V TTL Logic
Supports Live Insertion and Withdrawal
IOFF Specification Guarantees High Impedance When VCC = 0V
LVTTL Compatible
LVCMOS Compatible
24mA Balanced Output Sink and Source Capability
Near Zero Static Supply Current in All Three Logic States (10
A)
Substantially Reduces System Power Requirements
Latchup Performance Exceeds 500mA
ESD Performance: Human Body Model >2000V; Machine Model >200V
Pinout: 20Lead (Top View)
