Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at

General Description
The LCX574 is a high-speed, low power octal flip-flop
with a buffered common Clock (CP) and a buffered
common Output Enable (OE). The information presented
to the D inputs is stored in the flip-flops on the LOW-to-
HIGH Clock (CP) transition.
The LCX574 is functionally identical to the LCX374
except for the pinouts.
The LCX574 is designed for low voltage applications
with capability of interfacing to a 5V signal environment.
The LCX574 is fabricated with an advanced CMOS
technology to achieve high speed operation while main-
taining CMOS low power dissipation.

Note:
1. To ensure the high impedance state during power up
or down, OE should be tied to V
CC
through a pull-up
resistor: the minimum value of the resistor is
determined by the current-sourcing capability of the
driver.
