54LCX245

Low Voltage Bidirectional Transceiver with 5V Tolerant

Inputs and Outputs

General Description

Features

n 5V tolerant inputs and outputs

n 9ns t_PDmax, 10µA I_CCQmax

n Power down high impedance inputs and outputs

n Supports live insertion/withdrawal

n 2.0V–3.6V V_CCsupply operation

The LCX245 contains eight non-inverting bidirectional buff-

™

ers with TRI-STATE outputs and is intended for bus ori-

ented applications. The device is designed for low voltage

(3.3V) V_CCapplications 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.

24 mA output drive

n Implements patented noise/EMI reduction circuitry

n Functionally compatible with the 54 series 245

n ESD performance:

Human body model 2000V

Machine model 200V

The LCX245 is fabricated with an advanced CMOS technol-

ogy to achieve high speed operation while maintaining

CMOS low power dissipation.
