74AHCT14D,118

Overview

The Nexperia 74AHCT14D,118 is a hex inverting Schmitt trigger manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input levels. The device provides six inverting buffers with Schmitt-trigger action for noise immunity. It is housed in an SOIC-14 (SOT108) package with a body width of 3.9 mm. The component supports an ambient temperature range from -40 °C to +125 °C. Propagation delay is specified at 7.0 ns maximum at 5.5 V with 15 pF load capacitance.

Feature Summary

• Provides balanced propagation delays across all channels
• Features overvoltage tolerant inputs up to 5.5 V
• Includes high noise immunity via Schmitt-trigger action

Applications

• Signal translation between mixed voltage logic families
• Waveform shaping of slowly changing signals
• Jitter-free output signal generation

Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm that the automotive qualification status aligns with project requirements, as standard versions may differ from qualified variants. Ensure the datasheet revision corresponds to the latest manufacturing specifications before finalizing procurement orders.

Selection Notes

Select this component when TTL-compatible input thresholds are required alongside CMOS output drive capabilities. The Schmitt-trigger inputs make it suitable for noisy environments or applications involving slow-rise-time signals. Verify that the operating voltage remains strictly within the 4.5 V to 5.5 V range to ensure proper functionality and avoid exceeding absolute maximum ratings.

Part Context

This part belongs to the 74AHCT series, which bridges Low-power Schottky TTL (LSTTL) compatibility with advanced CMOS performance. The 'D' designation indicates the SOIC-14 plastic small outline package. The ',118' suffix typically denotes the specific packaging variant, such as cut tape or reel options available through distributors.

Replacement Considerations

Direct substitutes include other 74AHCT14 variants from different manufacturers offering identical pinouts and electrical characteristics. Verify package dimensions and thermal dissipation limits when swapping suppliers to ensure mechanical fit and reliability under similar operating conditions.
