74HC32DB,118

Overview

The Nexperia 74HC32DB,118 is a quad 2-input OR gate manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 6.0 V and features CMOS low power dissipation with high noise immunity. The device includes input clamp diodes for interfacing with voltages exceeding VCC. It provides symmetrical output impedance and balanced propagation delays. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Latch-up performance exceeds 100 mA per JESD 78 Class II Level B. It complies with JEDEC standards JESD8C and JESD7A. Operating temperature ranges from -40 °C to +125 °C.

Feature Summary

• Quad 2-input OR gate configuration
• Wide supply voltage range from 2.0 V to 6.0 V
• CMOS low power dissipation and high noise immunity
• Input clamp diodes for over-voltage interfacing

Applications

• General logic switching applications
• Signal routing in digital circuits
• Interface circuits requiring OR logic functionality

Procurement Notes

Verify the specific ordering suffix '118' against the manufacturer's current documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required operating temperature range and supply voltage conditions before procurement. Confirm RoHS compliance status as indicated in the latest product data sheet revision.

Selection Notes

Select this component when a quad 2-input OR gate is required within a 2.0 V to 6.0 V supply range. Consider the SO14 plastic small outline package (SOT108-1) for board space constraints. Verify that the CMOS input levels meet system requirements, as opposed to TTL levels found in HCT variants. Check ESD protection needs against application environment.

Part Context

This part belongs to the 74HC series of logic gates, specifically the 74HC32 family. It is a standard CMOS logic device widely used in digital electronics. The 'DB' designation indicates the SO14 package variant. It is distinct from the 74HCT32 which uses TTL input levels. The component is part of Nexperia's extensive portfolio of standard logic ICs.

Replacement Considerations

Direct replacements include other manufacturers' 74HC32 equivalents in SO14 packages. Cross-reference with 74HC32N or similar variants if pinout and electrical characteristics match. Ensure any substitute meets the same JEDEC standards and ESD protection ratings.
