74AC14SCX

Overview

The onsemi 74AC14SCX is a hex inverter integrated circuit belonging to the 74AC logic series. It utilizes CMOS technology and features Schmitt trigger inputs for noise immunity. The device contains six independent inverters within a single package. It operates with a supply voltage range of 2 V to 6 V. The maximum propagation delay is 15 ns at a load capacitance of 50 pF. Output drive capabilities include a high-level output current of -24 mA and a low-level output current of 24 mA. The component is housed in a 14-pin SOIC surface-mount package.

Feature Summary

• Hex inverter configuration with Schmitt trigger inputs
• CMOS construction for high-speed operation
• Wide operating voltage range from 2 V to 6 V

Applications

• Signal conditioning and waveform shaping
• Clock signal generation and buffering
• Noise filtering in digital circuits

Procurement Notes

Verify the specific suffix 'SCX' against the manufacturer's official datasheet to confirm the SOIC-14 package type and tape-and-reel packaging details. Ensure compatibility with the required 2 V to 6 V supply voltage range and check that the 15 ns propagation delay meets system timing requirements. Confirm RoHS compliance status through the latest product documentation before integration.

Selection Notes

Select this component when a hex inverter with hysteresis is required for noisy environments. The AC series offers higher speed than standard 74LS devices while maintaining CMOS power efficiency. Verify that the 14-pin SOIC footprint fits the PCB layout constraints. Consider the 24 mA output drive strength for driving moderate capacitive loads without external buffers.

Part Context

This part belongs to the 74AC family of high-speed CMOS logic devices produced by onsemi. The 74AC14 specifically designates a hex inverter with Schmitt triggers. It serves as a functional equivalent to other industry-standard hex inverters but is optimized for the AC performance characteristics defined by the manufacturer's specifications.

Replacement Considerations

Direct substitutes may include other manufacturers' 74AC14 variants in SOIC-14 packages, such as those from Texas Instruments or Nexperia, provided they match the pinout and electrical specifications.
