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 V
CC
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.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150
C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
