74AHCT04D,118

Overview

The Nexperia 74AHCT04D,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 an SO14 plastic small outline package (SOT108-1) with a body width of 3.9 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. Input levels are defined by TTL standards, while outputs provide balanced propagation delays.

Feature Summary

• Provides six independent inverting buffer circuits
• Accepts input voltages higher than the supply voltage
• Features ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model
• Ensures balanced propagation delays across all channels

Applications

• Signal inversion in digital logic circuits
• Interfacing between TTL-level inputs and CMOS-level outputs
• High-speed data processing applications requiring buffered signal paths

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the SO14 tape-and-reel packaging configuration. Confirm that the application environment remains within the specified -40 °C to +125 °C operating temperature range. Ensure supply voltage does not exceed the absolute maximum rating of 7.0 V to prevent permanent damage to the silicon gate structure.

Selection Notes

Select this component when TTL-compatible input thresholds are required for CMOS logic families. The AHCT series is appropriate for designs needing balanced propagation delays and high-speed performance. Verify that the SO14 package dimensions align with the PCB footprint requirements and that the thermal dissipation capabilities meet the system's power constraints under maximum load conditions.

Part Context

This part belongs to the 74AHC/AHCT logic family, which utilizes high-speed silicon-gate CMOS technology. The 'AHCT' designation specifically indicates compatibility with TTL input voltage levels while maintaining CMOS output characteristics. This family is designed to replace older LSTTL devices in modern systems without requiring level-shifting circuitry.

Replacement Considerations

Direct replacements include other manufacturers' 74AHCT04 variants in SOIC-14 packages. Ensure any substitute maintains the same SO14 pinout and electrical specifications regarding input/output voltage levels and propagation delay characteristics.
