SN74AHC14D

Overview

The SN74AHC14D is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features six independent inverting circuits. The device utilizes CMOS logic technology and is housed in a 14-pin SOIC package. Key electrical parameters include a propagation delay of 12 ns, high-level output current of -8 mA, and low-level output current of 8 mA. It supports surface mount installation and functions reliably across an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates six independent Schmitt-trigger inverters for signal conditioning
• Provides noise filtering capabilities through defined input hysteresis thresholds
• Supports wide supply voltage operation from 2 V to 5.5 V

Applications

• Signal wave shaping for noisy digital inputs
• Pulse width modulation generation
• Oscillator circuit implementation

Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-14 package configuration required for your design. Confirm RoHS compliance status via the manufacturer's official documentation before integration. Ensure the component meets the thermal requirements for your intended operating environment, as specifications may vary between standard and enhanced product grades.

Selection Notes

Select this component when multiple inverting stages with noise immunity are required in a single package. The AHC series offers improved speed and lower power consumption compared to legacy HC counterparts. Verify that the 14-pin SOIC footprint aligns with your PCB layout constraints and that the 2V to 5.5V supply range matches your system power rails.

Part Context

This part belongs to the SN74AHC14 family of hex Schmitt-trigger inverters. It is distinct from non-Schmitt variants like the SN74AHC04 and differs from the T-series which uses TTL-compatible input thresholds. The 'D' suffix specifically denotes the small-outline integrated circuit package type used in surface-mount applications.

Replacement Considerations

SN74AHC14DR serves as a reel-based alternative offering identical electrical characteristics and functionality within the same logic family.
