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 Semiconductors 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 www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

December 2013
74LCX574
Low Voltage Octal D-Type Flip-Flop
with 5V Tolerant Inputs and Outputs
Features General Description
5V tolerant inputs and outputs The LCX574 is a high-speed, low power octal flip-flop
with a buffered common Clock (CP) and a buffered
2.3V3.6V V specifications provided
CC
common Output Enable (OE
). The information presented
7.5ns t max. (V = 3.3V), 10A I max.
PD CC CC
to the D inputs is stored in the flip-flops on the LOW-to-
Power down high impedance inputs and outputs
HIGH Clock (CP) transition.
(1)
Supports live insertion/withdrawal
The LCX574 is functionally identical to the LCX374
24mA output drive (V = 3.0V)
CC
except for the pinouts.
Implements proprietary noise/EMI reduction circuitry
The LCX574 is designed for low voltage applications
Latch-up performance exceeds JEDEC 78 conditions
with capability of interfacing to a 5V signal environment.
ESD performance
The LCX574 is fabricated with an advanced CMOS
Human body model > 2000V
technology to achieve high speed operation while main-
Machine model > 200V
taining CMOS low power dissipation.
Note:
1. To ensure the high impedance state during power up
or down, OE
should be tied to V through a pull-up
CC
resistor: the minimum value of the resistor is
determined by the current-sourcing capability of the
driver.
