1998 Nov 12

853-2134 20359

FEATURES

• 4-bit 74LVT125-like bus driver

• 8-bit 74LVT14-like Schmitt trigger

• Bus drive +64mA/–32mA

• 7 bus inputs with common inversion control pin

• 32-pin TSSOP footprint

• DE pin with resistive pull up and active LOW for easier live

insertion

• DE pin includes Schmitt trigger with typical 0.6V hysteresis

DESCRIPTION

The 74LVT1403 is a high-performance BiCMOS product designed

for VCC operation at 3.3V.

This device combines the functionality of a 4-bit data path bus driver

and 8-bit Schmitt trigger bus receiver, along with control logic in one

32-pin package.

The receiver inputs are Schmitt trigger type capable of transforming

slowly changing input signals into sharply defined, jitter-free output

signals. The receiver outputs are 74LVT14 style with +32mA/–20mA

drive capability. The receiver inputs include the bus hold feature.

The driver outputs feature power-up in 3-State/live insertion

capability and are all controlled by the A/B, EN1, and EN2 control

pins. The driver inputs include the bus hold feature.
