74HC32D/AUJ

Overview

The 74HC32D/AUJ is a quad 2-input OR gate manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features CMOS low power dissipation, high noise immunity, and symmetrical output impedance with balanced propagation delays. Inputs include clamp diodes for interfacing with voltages exceeding VCC. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Latch-up performance complies with JESD 78 Class II Level B.

Feature Summary

• Quad 2-input OR logic function
• Wide supply voltage operation from 2.0 V to 6.0 V
• High noise immunity and CMOS low power dissipation
• Robust ESD protection and latch-up performance

Applications

• General-purpose digital logic circuits
• Signal routing and switching applications
• Interface circuits requiring voltage level translation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Confirm RoHS compliance status and REACH requirements prior to procurement. Ensure design-in specifications match the latest product data sheet revision to avoid discrepancies in electrical characteristics or pinout definitions.

Selection Notes

Select this component for designs requiring standard quad OR gate functionality with wide voltage tolerance. Verify that the SO14 plastic small outline package dimensions meet board space constraints. Consider the input clamp diode feature when interfacing with signals potentially exceeding the supply rail. Ensure operating conditions remain within the specified absolute maximum ratings to prevent permanent damage.

Part Context

This part belongs to the 74HC/HCT logic family, designed for CMOS technology applications. It serves as a fundamental building block for combinational logic circuits. The 'D' suffix indicates the SO14 package variant. The AUJ designation typically refers to specific manufacturing or packaging details defined by the supplier.
