SN74ACT14N

Overview

The SN74ACT14N is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It features six independent inverters with Schmitt-trigger inputs, providing noise filtering and hysteresis for signal conditioning. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL-compatible input levels. It is housed in a 14-pin PDIP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides hysteresis via Schmitt-trigger inputs to filter noisy signals
• TTL-voltage compatible inputs for direct interfacing
• Bipolar speed performance with reduced power consumption

Applications

• Signal conditioning for noisy digital lines
• Waveform shaping from slow or distorted edges
• Threshold detection circuits

Procurement Notes

Verify the specific suffix 'N' confirms the 14-pin PDIP through-hole package variant. Confirm RoHS compliance status as required by your assembly specifications. Ensure the operating temperature range meets your environmental constraints. Cross-reference the manufacturer part number against official Texas Instruments documentation to avoid counterfeit components.

Selection Notes

Select this component when noise immunity is critical for inverting logic signals. The Schmitt-trigger action distinguishes it from standard inverters lacking hysteresis. Consider the PDIP package only if through-hole mounting is mandatory. Evaluate propagation delay requirements against the ACT series specifications for timing-sensitive designs.

Part Context

This part belongs to the Texas Instruments ACT (Advanced CMOS Technology) logic family. It combines the high speed of bipolar logic with low power consumption. The SN74ACT14N is functionally equivalent to other hex Schmitt-trigger inverters but offers specific packaging and electrical characteristics defined by the ACT series standards.

Replacement Considerations

Check for SN74ACT14DRG4 for SOIC surface-mount alternatives. Verify pinout compatibility before substituting with generic hex inverters. Ensure replacement parts maintain TTL input compatibility and similar hysteresis voltage levels.
