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.

74LCX245
Low Voltage Bidirectional Transceiver with 5V Tolerant
Inputs and Outputs
Features General Description
5V tolerant inputs and outputs The LCX245 contains eight non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus
2.3V to 3.6V V specifications provided
CC
oriented applications. The device is designed for low
7.0ns t max. (V = 3.3V), 10A I max.
PD CC CC
voltage (2.5V and 3.3V) V
applications with capability
CC
Power down high impedance inputs and outputs
of interfacing to a 5V signal environment. The T/R input
(1)
Supports live insertion/withdrawal
determines the direction of data flow through the device.
24mA output drive (V = 3.0V)
The OE input disables both the A and B ports by placing
CC
them in a high impedance state.
Implements proprietary noise/EMI reduction circuitry
Latch-up performance exceeds 500mA
The LCX245 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintain-
ESD performance:
ing CMOS low power dissipation.
Human body model > 2000V
Machine model > 200V
Leadless DQFN package
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 or the resistor is
determined by the current-sourcing capability of the
driver.
