74ACT14SCX

Overview

The onsemi 74ACT14SCX is a hex inverter integrated circuit belonging to the 74ACT logic family. It features Schmitt trigger inputs for noise immunity and operates within a supply voltage range of 4.5 V to 5.5 V. The device provides high-level output currents of -24 mA and low-level output currents of 24 mA. It is housed in a 14-pin SOIC surface-mount package with an operating temperature range from -40°C to +85°C.

Feature Summary

• Hex inverter configuration with six independent channels
• Schmitt trigger input structure for signal conditioning
• CMOS technology ensuring low static power consumption
• High drive capability with symmetric output currents

Applications

• Signal wave shaping and pulse generation
• Oscillator circuits requiring hysteresis
• Noise filtering in digital communication lines
• Clock signal conditioning for microcontrollers

Procurement Notes

Verify the specific suffix 'SCX' against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the part number with official distributor catalogs to avoid obsolete or counterfeit components, as suffixes may indicate regional or packaging variations not always detailed in generic listings.

Selection Notes

Select this component when Schmitt trigger functionality is required within a 5V CMOS logic environment. The 74ACT series offers faster propagation delays compared to standard 74HC devices while maintaining compatibility with TTL logic levels. Verify that the application does not require extended temperature ranges beyond +85°C or higher voltage tolerance than 5.5V. Consider pin-compatible alternatives if different package styles are needed for PCB layout constraints.

Part Context

This component is part of the broader 74ACT logic family produced by onsemi, designed for high-speed digital applications. It shares functional similarities with other hex inverters but is distinguished by its ACT speed grade and Schmitt trigger inputs. The 74ACT series bridges the performance gap between older TTL technologies and modern HC/HCT families, offering improved switching speeds at 5V operation.
