74AHCT14BQ,115

Overview

The Nexperia 74AHCT14BQ,115 is a hex inverting Schmitt trigger integrated circuit belonging to the 74AHCT logic family. It features TTL-compatible input levels and operates within a supply voltage range of 4.5 V to 5.5 V. The device contains six independent inverters with Schmitt-trigger inputs, providing high noise immunity and balanced propagation delays. It is housed in a DHVQFN14 package (SOT762-1) with dimensions of 2.5 mm x 3 mm x 0.85 mm. The component supports an ambient operating temperature range from -40 °C to +125 °C.

Feature Summary

• Hex inverter configuration with Schmitt-trigger inputs for signal conditioning
• TTL-compatible input switching levels for direct interfacing with TTL logic
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• High noise immunity and CMOS low power dissipation characteristics

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators
• Translators in mixed voltage environments

Selection Notes

Select this component when TTL-level compatibility is required alongside Schmitt-trigger action for noisy digital signals. The DHVQFN14 package offers a compact surface-mount solution suitable for space-constrained designs. Ensure the application environment remains within the specified 4.5 V to 5.5 V supply voltage range and the -40 °C to +125 °C temperature limits for optimal performance.

Part Context

This part belongs to the 74AHCT series, which bridges CMOS technology with TTL logic levels. The 'BQ' suffix denotes the DHVQFN14 package variant, while ',115' indicates the standard tape and reel packaging quantity. It shares functional similarities with other hex inverters but is distinguished by its specific input threshold characteristics and package form factor.

Replacement Considerations

Direct pin-to-pin replacements may include other 74AHCT14 variants in different packages, such as the SO14 or TSSOP14 versions, provided the electrical specifications match. Cross-family replacements like 74HC14 require verification of input level compatibility.
