SN74ACT14DRG4

Overview

The SN74ACT14DRG4 is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features six independent inverting channels. The device utilizes a 14-pin Small Outline Integrated Circuit (SOIC) package with a lead pitch of 0.25 inches. It supports a maximum load capacitance of 50 pF and provides a maximum output current of 24 mA. The component is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates hysteresis into the switching threshold to filter noisy input signals effectively.
• Provides high noise immunity through defined voltage thresholds for logical transitions.
• Delivers strong drive capability suitable for interfacing with various digital loads.

Applications

• Signal conditioning for noisy digital environments
• Waveform shaping of slow-rise or slow-fall time signals
• Oscillator circuit design requiring stable switching thresholds

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free material declarations directly with the supplier. Ensure the procurement channel sources genuine components to avoid counterfeit risks associated with integrated logic circuits.

Selection Notes

Select this component when signal integrity requires noise rejection via hysteresis rather than standard logic inversion. Compare propagation delay characteristics against other ACT series variants if timing constraints are critical. Verify that the SOIC-14 footprint aligns with existing board layout requirements before finalizing the bill of materials.

Part Context

This part belongs to the SN74ACT family, which combines the speed of Advanced CMOS technology with TTL-compatible pinouts. It serves as a functional upgrade over older HC or HCT series inverters where faster switching speeds and lower power consumption are necessary while maintaining backward compatibility with existing system architectures.

Replacement Considerations

SN74ACT14D is a tube-packaged equivalent offering identical electrical performance. SN74ACT14N provides a PDIP-14 alternative for through-hole applications. Cross-reference datasheets to confirm package dimensions and thermal characteristics match the target design constraints.
