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

74LCX760
Low Voltage Buffer/Line Driver
with 5V Tolerant Inputs and Open Drain Outputs
General Description
Features
■ Open drain version of the LCX244
The LCX760 is the Open Drain version of the LCX244. The
LCX760 contains eight non-inverting buffers with 3-STATE
outputs. The device may be employed as a memory
address driver, clock driver and bus-oriented transmitter/
receiver. The LCX760 is designed for low voltage (2.5V or
3.3V) VCC applications with capability of interfacing to a 5V
■ 5V tolerant inputs and outputs
■ 2.3V–3.6V VCC specifications provided
■ 8.0 ns tPD max (VCC 3.3V), 10 A ICC max
■ Power down high impedance inputs and outputs
■ Supports live insertion/withdrawal (Note 1)
■ 24 mA output drive (VCC 3.0V)
signal environment.
The LCX760 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
■ Implements proprietary noise/EMI reduction circuitry
■ Latch-up conforms to JEDEC JED78
■ ESD performance:
Human body model 2000V
Machine model 200V
Note 1: To ensure the high-impedance state during power up or down, OE
should be tied to V
through a pull-up resistor: the minimum value or the
CC
resistor is determined by the current-sourcing capability of the driver.
