74VCXH245

Low Voltage Bidirectional Transceiver with Bushold

General Description

Features

The VCXH245 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. The VCXH245

data inputs include active bushold circuitry, eliminating the

need for external pull-up resistors to hold unused or float-

ing data inputs at a valid logic level.

■ 1.2V to 3.6V V_CCsupply operation

■ Bushold on data inputs eliminates the need for external

pull-up/pull-down resistors

■ t_PD

3.5 ns max for 3.0V to 3.6V V_CC

■ Static Drive (I_OH/I_OL

)

24 mA @ 3.0V V_CC

The 74VCXH245 is designed for low voltage (1.2V to 3.6V)

■ Uses patented Quiet Series noise/EMI reduction

V_CCapplications.

circuitry

The 74VCXH245 is fabricated with an advanced CMOS

technology to achieve high-speed operation while main-

taining low CMOS power dissipation.

■ Latchup performance exceeds 300 mA

■ ESD performance:

Human body model 2000V

Machine model 200V
