74HC20D-Q100,118

Overview

The 74HC20D-Q100,118 is a dual 4-input NAND gate from Nexperia, packaged in an SO14 (SOT108-1) plastic small outline package with 14 leads. 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 input clamp diodes for interfacing with voltages exceeding VCC. It complies with JEDEC standards JESD8C and JESD7A, offering ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

Feature Summary

• Qualified to AEC-Q100 Grade 1 for automotive applications
• Includes input clamp diodes for extended voltage interfacing
• Provides robust ESD protection via HBM and CDM standards
• Exhibits high noise immunity and CMOS low power characteristics

Applications

• Automotive electronic systems requiring Grade 1 qualification
• Digital logic circuits utilizing dual 4-input NAND functionality
• Interfaces requiring current limiting resistors for input protection

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74HC20D-Q100 designation corresponds to the SO14 package. Confirm that the temperature range and voltage specifications align with your system's operational limits. Ensure compliance with AEC-Q100 requirements if used in automotive contexts. Cross-reference the latest datasheet revision for any updates to pin configurations or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a dual 4-input NAND gate with automotive qualification is required. The SO14 package is suitable for surface-mount applications needing a compact footprint. Consider the wide supply voltage range and operating temperature span for harsh environments. Verify that the input clamp diode feature meets interface needs without external protection components. Ensure the latch-up performance meets system reliability standards.

Part Context

This part belongs to the 74HC20-Q100 family of dual 4-input NAND gates designed for automotive use. The 'D' in the model number indicates the SO14 package variant, distinct from the PW suffix which denotes TSSOP14. The family shares identical logical functions and electrical characteristics across packages, differing only in physical dimensions and thermal properties. This specific item is a production-grade product data sheet release.

Replacement Considerations

The 74HC20PW-Q100 serves as a package alternative in the same functional family, utilizing a TSSOP14 housing instead of SO14. Both variants share identical electrical specifications and automotive qualifications. Substitution requires verifying board space compatibility between the two package types.
