74ALVC245

Low Voltage Bidirectional Transceiver

with 3.6V Tolerant Inputs and Outputs

General Description

Features

■ 1.65V to 3.6V V_CCsupply operation

The ALVC245 contains eight non-inverting bidirectional

buffers with 3-STATE outputs and is intended for bus ori-

ented applications. The T/R input determines the direction

of data flow. The OE input disables both the A and B ports

by placing 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 74ALVC245 is designed for low voltage (1.65V to

3.6V) V_CCapplications with I/O compatibility up to 3.6V.

3.4 ns max for 3.0V to 3.6V V_CC

3.9 ns max for 2.3V to 2.7V V_CC

6 ns max for 1.65V to 1.95V V_CC

The 74ALVC245 is fabricated with an advanced CMOS

technology to achieve high-speed operation while main-

taining low CMOS power dissipation.

■ Uses patented Quiet Series noise/EMI reduction

circuitry

■ Latchup conforms to JEDEC JED78

■ ESD performance:

Human body model 2000V

Machine model 200V

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

down, OE should be tied to V

through a pull up resistor. The minimum

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

driver.
