MC74LCX574
Low−Voltage CMOS
Octal D−Type Flip−Flop
Flow Through Pinout
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
The MC74LCX574 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
switching noise performance. A VI specification of 5.5 V allows
MC74LCX574 inputs to be safely driven from 5.0 V devices.
The MC74LCX574 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. The LCX574 flow through design facilitates easy PC
board layout.
