74VCX245

Low Voltage Bidirectional Transceiver

with 3.6V Tolerant Inputs and Outputs

General Description

Features

■ 1.4V to 3.6V V_CCsupply operation

The VCX245 contains eight non-inverting bidirectional buff-

ers with 3-STATE outputs and is intended for bus oriented

applications. The T/R input determines the direction of data

flow. The OE input disables both the A and B ports by plac-

ing them in a high impedance state.

■ 3.6V tolerant inputs and outputs

■ Power-off high impedance inputs and outputs

■ Supports Live Insertion and Withdrawal (Note 1)

■ t_PD

The 74VCX245 is designed for low voltage (1.4V to 3.6V)

V_CCapplications with I/O compatibility up to 3.6V.

3.5 ns max for 3.0V to 3.6V V_CC

The 74VCX245 is fabricated with an advanced CMOS

technology to achieve high-speed operation while main-

taining low CMOS power dissipation.

■ Static Drive (I_OH/I_OL

)

±24 mA @ 3.0V V_CC

■ Uses patented noise/EMI reduction

circuitry

■ Latchup performance exceeds 300 mA

■ ESD performance:

Human body model > 2000V

Machine model > 200V

Note 1: To ensure the high impedance state during power up and power

down, OE_nshould be tied to V_CCthrough a pull up resistor. The minimum

value of the resistor is determined by the current sourcing capability of the

driver.
