74ALVC32PW,112

Overview

The Nexperia 74ALVC32PW,112 is a quad 2-input OR gate in a TSSOP14 package. It operates on a supply voltage range of 1.65 V to 3.6 V and supports an ambient temperature from -40 °C to +125 °C. The device features Schmitt trigger inputs for slow signal tolerance and IOFF circuitry for partial power-down protection. Propagation delay ranges from 1.0 ns to 5.4 ns depending on voltage and temperature.

Feature Summary

• Schmitt trigger action on all inputs provides tolerance for slow rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow current.
• Overvoltage tolerant inputs allow direct interfacing with TTL levels.

Applications

• Partial power down applications
• Mixed voltage logic translation
• General purpose digital logic processing

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP14 (SOT402-1) package variant. Confirm the required operating temperature range matches the datasheet specifications for your application environment. Ensure input signals remain within the specified voltage limits to avoid exceeding absolute maximum ratings.

Selection Notes

Select this component when a quad 2-input OR function is required with low power consumption and high noise immunity. The wide supply voltage range makes it suitable for various CMOS logic families. Verify that the TSSOP14 package dimensions fit the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the 74ALVC family of advanced low-voltage CMOS logic devices. The 74ALVC32 series specifically provides four independent OR gates. The PW suffix indicates the plastic thin shrink small outline package with 14 leads.

FAQ

How does the IOFF feature benefit the circuit?

The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current through the device.

What is the input voltage tolerance?

The inputs are overvoltage tolerant up to 3.6 V, allowing direct interface with TTL levels even when the supply voltage is lower.
