74AHCT04PW,118

Overview

The Nexperia 74AHCT04PW,118 is a high-speed Si-gate CMOS hex inverter compliant with JEDEC standard No. 7-A and pin-compatible with Low-power Schottky TTL (LSTTL). It contains six independent inverting buffers housed in a TSSOP14 plastic thin shrink small outline package (SOT402-1) with a body width of 4.4 mm. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. It features balanced propagation delays and inputs that accept voltages higher than VCC.

Feature Summary

• TTL input levels for direct interfacing with LSTTL logic systems
• ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model
• Balanced propagation delays across all channels

Applications

• Signal inversion in digital logic circuits
• Interfacing between TTL and CMOS logic domains
• Clock signal buffering and conditioning

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple options including SO14 and DHVQFN14. Confirm the temperature grade aligns with system requirements, noting the specified range extends to +125 °C. Ensure compliance with RoHS3 standards and check for any recent Product Change Notifications regarding labeling or assembly updates before finalizing procurement orders.

Selection Notes

Select this component when TTL-level input compatibility is required alongside CMOS output performance. The TSSOP14 package offers a compact footprint suitable for space-constrained designs. Verify that the operating supply voltage remains strictly within the 4.5 V to 5.5 V range to ensure correct logic threshold behavior and prevent damage to the internal circuitry during operation.

Part Context

This component belongs to the 74AHC/AHCT logic family, designed for high-speed applications requiring low power consumption. The 'AHCT' designation specifically indicates compatibility with TTL input voltage levels while maintaining CMOS drive capabilities. It serves as a fundamental building block for complex digital systems requiring signal inversion and level shifting between different logic families.

Replacement Considerations

Direct pin-compatible substitutes include the 74AHC04 variants from the same manufacturer. Cross-brand replacements must verify identical pinout configurations, supply voltage ranges, and logic level compatibility to ensure seamless integration without redesigning the surrounding circuitry.

FAQ

What are the specific input voltage thresholds for the 74AHCT04?

For the 74AHCT04 variant, the HIGH-level input voltage minimum is 2.0 V, and the LOW-level input voltage maximum is 0.8 V when operating at supply voltages between 4.5 V and 5.5 V.

How does the ESD protection rating compare to industry standards?

The device exceeds ANSI/ESDA/JEDEC JS-001 class 2 requirements with over 2000 V Human Body Model protection and exceeds ANSI/ESDA/JEDEC JS-002 class C3 requirements with over 1000 V Charged Device Model protection.
