74AHCT04D,112

Overview

The Nexperia 74AHCT04D,112 is a high-speed Si-gate CMOS hex inverter compliant with JEDEC standard No. 7-A and pin-compatible with LSTTL. It 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. The device features balanced propagation delays, TTL input levels, and ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Packaged in SO14 (SOT108-1), it provides six inverting buffers with inputs accepting voltages higher than VCC.

Feature Summary

• Provides six independent inverting buffers compatible with Low-power Schottky TTL (LSTTL) pinouts.
• Accepts TTL logic input levels while operating as a high-speed CMOS device.
• Includes robust electrostatic discharge protection meeting ANSI/ESDA/JEDEC standards.

Applications

• Signal inversion in mixed-voltage digital environments
• Clock signal buffering and conditioning
• Logic level translation between TTL and CMOS domains

Procurement Notes

Verify the specific ordering suffix '112' against current Nexperia documentation to confirm tube packaging and availability status. Confirm that the component meets RoHS3 compliance requirements for your target market. Ensure design-in validation accounts for the specified -40 °C to +125 °C operating temperature range and absolute maximum ratings to prevent device stress.

Selection Notes

Select this component when TTL-compatible input thresholds are required alongside CMOS performance characteristics. The SO14 package offers a compact surface-mount solution suitable for space-constrained designs. Verify that the 4.5 V to 5.5 V supply voltage range aligns with the system power architecture before integration.

Part Context

This part belongs to the 74AHCT04 family of hex inverters manufactured by Nexperia. It shares functional specifications with the 74AHC04 variant but differs in input threshold compatibility, specifically supporting TTL levels. The D suffix indicates the SO14 plastic small outline package, while the 112 suffix denotes the specific tape and reel or tube configuration.

Replacement Considerations

Direct substitutes include other 74AHCT04 variants from Nexperia such as the 74AHCT04PW (TSSOP14) or 74AHCT04BQ (DHVQFN14), provided the package footprint is adaptable. Cross-manufacturer equivalents must be verified for identical pinout, electrical characteristics, and thermal performance.
