74AHC14D,112

Overview

The Nexperia 74AHC14D,112 is a hex inverting Schmitt trigger integrated circuit manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device utilizes a SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm. It provides balanced propagation delays and high noise immunity, making it suitable for mixed voltage environments. The component supports an ambient operating temperature range from -40 °C to +125 °C.

Feature Summary

• Hex inverter configuration with Schmitt-trigger inputs
• Overvoltage tolerant inputs up to 5.5 V
• Balanced propagation delays and high noise immunity

Applications

• Signal conditioning for slowly changing input signals
• Translators in mixed voltage environments
• Relaxation oscillator circuits

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the SO14 package variant when sourcing. Confirm that the procurement channel sources directly from Nexperia or authorized distributors to ensure authenticity. Check current product status as availability may vary across regions. Ensure compliance with RoHS directives and REACH regulations relevant to your manufacturing location before finalizing orders.

Selection Notes

Select this component when a hex inverter with Schmitt-trigger action is required for signal shaping. The 74AHC14D variant specifically requires the SO14 package format. Consider the 74AHCT14 series if TTL input levels are necessary instead of CMOS levels. Evaluate the power dissipation limits and thermal derating requirements based on the specific ambient temperature conditions of the target application environment.

Part Context

This part belongs to the 74AHC/AHCT logic family, which consists of high-speed Si-gate CMOS devices. These components are pin-compatible with Low-power Schottky TTL (LSTTL). The 74AHC14D,112 represents the AHC variant designed for CMOS input levels, distinct from the AHCT variant which supports TTL input levels. Both variants share similar electrical characteristics and package options within the broader family.

Replacement Considerations

The 74AHCT14D,112 serves as a functional substitute if TTL input compatibility is acceptable. Other package variants such as 74AHC14PW,118 (TSSOP14) or 74AHC14BQ,115 (DHVQFN14) offer alternative form factors but require PCB layout modifications.
