SN74ACT14NSR

Overview

The SN74ACT14NSR is a hex inverter from Texas Instruments, belonging to the SN74ACT logic family. It features TTL-compatible Schmitt-trigger inputs designed to support slow and noisy input signals. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 14-pin SOIC surface-mount package. It provides continuous output drive capabilities suitable for driving transmission lines.

Feature Summary

• TTL-compatible Schmitt-trigger inputs enable reliable operation with slow or noisy signals
• Capable of driving 50-ohm transmission lines directly
• Provides continuous ±24 mA output drive current at 5 V

Applications

• Inverting digital signals
• Debouncing switches
• Synchronous inverting of clock inputs

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets required operating temperature ranges and electrical characteristics for the target application environment before procurement.

Selection Notes

Select this component when Schmitt-trigger action is required to clean up noisy waveforms. The ACT series offers faster propagation delays compared to standard HC devices while maintaining CMOS power efficiency. Verify that the 4.5 V to 5.5 V supply range aligns with the system design.

Part Context

This part belongs to the SN74ACT family of high-speed CMOS logic devices manufactured by Texas Instruments. The family includes various logic functions such as inverters, gates, and flip-flops, all characterized by TTL-compatible inputs and fast switching speeds suitable for advanced digital systems.

Replacement Considerations

Check for direct equivalents like the SN74ACT14N or other variants within the SN74ACT14 series. Confirm pinout compatibility and ensure any substitute maintains the same Schmitt-trigger input characteristics and output drive capabilities.
