SN74HC7032D

Inverter Gates Overview

The SN74HC7032D is a quadruple 2-input OR gate with Schmitt-trigger inputs in a 14-pin SOIC package. It operates from 2 V to 6 V, features balanced CMOS push-pull outputs, and consumes low power (20-µA max ICC). Propagation delay ranges from 14 ns at 6 V to 163 ns at 2 V. Hysteresis voltage spans 0.2 V to 2.5 V depending on supply.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide hysteresis for tolerance to slow or noisy signals
• Balanced CMOS push-pull outputs allow similar sourcing and sinking currents
• Low static power consumption of 20 µA maximum supply current

Inverter Gates Applications

• Monitoring error signals using fewer inputs
• Combining active-low enable signals
• Directly controlling fan driver enable pins via overheat signals

Inverter Gates Procurement Notes

Verify the specific ordering suffix against the Package Option Addendum to confirm packaging type. The 'D' suffix indicates a standard tube package containing 50 units. Confirm moisture sensitivity level and lead finish details match system requirements before procurement.

Inverter Gates Selection Notes

Select this component when noise immunity is required due to its Schmitt-trigger architecture. Ensure output capacitive loads remain below 50 pF for optimal performance. Verify that the 2 V to 6 V operating range aligns with the target system's supply voltage constraints.
