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

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Recommended Operating Conditions(5)
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to absolute maximum ratings.
