SN74AC14PWRE4

Overview

The SN74AC14PWRE4 is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports a low-level output current of 24 mA and a high-level output current of -24 mA. The device features a propagation delay of 11 ns and functions across an operating temperature range from -40 °C to +85 °C. It utilizes a 14-pin TSSOP surface-mount package.

Feature Summary

• Integrates six independent Schmitt-trigger inverters for signal conditioning
• Provides robust noise filtering through defined input hysteresis thresholds
• Supports wide supply voltage operation from 2 V to 6 V
• Delivers high drive capability with 24 mA output currents

Applications

• Signal wave shaping for noisy digital environments
• Transition time controllers for clock signals
• Oscillator circuits requiring stable switching thresholds

Procurement Notes

Verify the E4 suffix indicates lead-free composition compliant with RoHS standards. Confirm the TSSOP-14 package dimensions match the design footprint. Ensure the AC logic family specifications align with system voltage requirements. Check for specific manufacturing date codes if long-term availability is critical.

Selection Notes

Select this component when Schmitt-trigger action is required for clean signal inversion. The AC series offers higher speed than standard LS logic while maintaining CMOS power efficiency. Verify that the 2 V to 6 V operating range covers all intended supply rails. Consider the TSSOP-14 package for space-constrained surface-mount designs.

Part Context

This part belongs to the SN74AC14 family of hex Schmitt-trigger inverters. The PWRE4 designation specifies the TSSOP-14 package, reel tape packaging, and lead-free construction. It serves as a functional equivalent to other AC-series inverters with Schmitt inputs, providing standardized digital logic performance.
