74AHCT00D/S400,118

Overview

The Nexperia 74AHCT00D/S400,118 is a quad 2-input NAND gate from the 74AHCT00 series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input levels. The device includes overvoltage tolerant inputs up to 5.5 V, Schmitt-trigger actions on all inputs, and balanced propagation delays. It provides high noise immunity and low power dissipation typical of CMOS technology. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Latch-up performance meets JESD 78 Class II Level A standards. The component is specified for ambient temperatures ranging from -40 °C to +125 °C.

Feature Summary

• Quad 2-input NAND logic function with balanced propagation delays
• TTL input levels compatible with standard digital interfaces
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• Schmitt-trigger action on all inputs for improved noise immunity

Applications

• Signal translation between mixed voltage domains
• General purpose digital logic processing
• Noise-immune signal buffering in industrial environments

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and tape/reel specifications. Ensure the requested variant matches the required thermal and electrical characteristics for the target application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS output drive capabilities. The wide operating temperature range supports demanding industrial applications. Verify that the system supply voltage remains within the 4.5 V to 5.5 V recommended limits to ensure proper logic level thresholds and propagation delay performance.

Part Context

This part belongs to the 74AHCT00 family of high-speed Si-gate CMOS devices. It is pin-compatible with Low-power Schottky TTL (LSTTL) standards. The 'D' designation indicates an SO14 plastic small outline package. The 'S400' suffix typically denotes specific packaging or handling variations defined by Nexperia's internal coding systems.

Replacement Considerations

Direct replacements include other 74AHCT00 variants from Nexperia such as 74AHCT00PW or 74AHCT00BQ, provided the package footprint matches the design constraints. Other manufacturers offering JEDEC-compliant 74AHCT00 parts may be suitable if electrical parameters align.
