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

oriented applications. The device is designed for low

■ 2.3V to 3.6V V specifications provided

■ 7.0ns t max. (V = 3.3V), 10µA I max.

voltage (2.5V and 3.3V) V applications with capability

■ Power down high impedance inputs and outputs

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.

(1)

■ Supports live insertion/withdrawal

■

24mA output drive (V = 3.0V)

■ Implements proprietary noise/EMI reduction circuitry

■ Latch-up performance exceeds 500mA

■ ESD performance:

The LCX245 is fabricated with an advanced CMOS tech-

nology to achieve high speed operation while maintain-

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

resistor: the minimum value or the resistor is

determined by the current-sourcing capability of the

driver.
