74LVC374A D

74LVC374A
Low-Voltage CMOS Octal
D-Type Flip-Flop
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
www.onsemi.com
The 74LVC374A is a high performance, non−inverting octal D−type
flip−flop operating from a 1.2 to 3.6 V 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 5.5 V allows 74LVC374A inputs to
be safely driven from 5 V devices.
The 74LVC374A 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.
