74HC32D-Q100,118

Overview

The Nexperia 74HC32D-Q100,118 is a quad 2-input OR gate qualified to AEC-Q100 Grade 1 for automotive use. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS low power dissipation, high noise immunity, and latch-up performance exceeding 100 mA per JESD 78 Class II Level B. Inputs include clamp diodes for interfacing with voltages exceeding VCC. It complies with JEDEC standards JESD8C (2.7 V to 3.6 V) and JESD7A (2.0 V to 6.0 V).

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1.
• Wide supply voltage range from 2.0 V to 6.0 V.
• Specified operating temperature range from -40 °C to +125 °C.
• High noise immunity and symmetrical output impedance.

Applications

• Automotive electronic systems requiring logic gating.
• Industrial control circuits operating at extended temperatures.
• General-purpose digital logic applications.

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74HC32 family includes SO14, TSSOP14, and DHVQFN options. Confirm that the design requirements align with the specified AEC-Q100 Grade 1 qualification level. Ensure input voltage levels do not exceed absolute maximum ratings to prevent damage. Check for any recent product change notices regarding pin configurations or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a quad 2-input OR gate is needed for automotive environments. The HC series provides CMOS compatibility with standard logic levels. Consider the SO14 package for standard surface-mount assembly. Verify that the propagation delay and power dissipation characteristics meet the system timing and thermal constraints. Ensure the application does not require TTL-level inputs, which would necessitate the HCT variant.

Part Context

This part belongs to the Nexperia 74HC32-Q100 family of quad 2-input OR gates. It is designed for robust performance in harsh environments, featuring high latch-up protection and wide supply voltage tolerance. The D suffix indicates the SO14 plastic small outline package. The Q100 designation confirms its automotive qualification status.

Replacement Considerations

Direct functional equivalents within the same family include the 74HCT32D-Q100,118 for TTL-compatible inputs. Other package variants like 74HC32PW-Q100 or 74HC32BQ-Q100 offer different form factors but identical logical functionality. Cross-referencing with other manufacturers' 74HC32 parts requires verifying voltage ranges and package dimensions.
