SN74ACT14PWRG4

Overview

The SN74ACT14PWRG4 is a hex Schmitt-trigger inverter from Texas Instruments, part of the ACT logic series. It features six independent inverters with TTL-compatible Schmitt-trigger inputs to handle slow and noisy signals. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides continuous output drive currents of ±24 mA at 5 V and supports short-term drives up to ±75 mA. The propagation delay is typically 12.5 ns. It is housed in a 14-pin TSSOP package and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• TTL-compatible Schmitt-trigger inputs effectively support slow and noisy input signals
• Capable of driving 50-ohm transmission lines with robust output drive capabilities
• Provides continuous ±24 mA output drive current at 5 V for reliable signal integrity

Applications

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

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and lead-free status as per manufacturer specifications. Confirm the TSSOP-14 package type matches the design requirements. Check for obsolescence notices or end-of-life notifications directly from Texas Instruments, as availability may be limited. Ensure the operating temperature range aligns with the intended environmental conditions.

Selection Notes

Select this component when noise immunity is critical due to its Schmitt-trigger input characteristics. It is suitable for applications requiring precise timing inversion with moderate speed. Consider the 4.5 V to 5.5 V supply voltage constraint during power budgeting. The TSSOP package offers a compact solution for surface-mount designs where space is constrained.

Part Context

This device belongs to the SN74ACT family, which combines the high-speed performance of AC logic with CMOS low power consumption. The SN74ACT14 variant specifically integrates Schmitt triggers for enhanced noise rejection. It serves as a standard interface component in digital systems requiring signal conditioning and inversion.

Replacement Considerations

SN74ACT14DRG4 is a verified alternative in the SOIC-14 package.
