3.3V combined 8-bit bus receiver
and 4-bit bus driver
74LVT1403
FEATURES
DESCRIPTION
• 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
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.
insertion
• DE pin includes Schmitt trigger with typical 0.6V hysteresis
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.

NOTES:
1. All typical values are at VCC = 3.3V and Tamb = 25°C.
2. This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
3. This parameter is valid for any VCC between 0V and 1.2V with a transition time of up to 10msec. From VCC = 1.2V to VCC = 3.3V ± 0.3V, a
transition time of 100µsec is permitted. This parameter is valid for Tamb = 25°C only.
4. Unused pins at VCC or GND.
5. All RYn outputs High. All DYn outputs pulled up to VCC or pulled down to ground.
