SN74AHC14PWE4

Overview

The SN74AHC14PWE4 is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features six independent inverting channels. The device utilizes a 14-TSSOP surface-mount package. Key electrical parameters include a propagation delay of 10.6 ns at 5 V with a 50 pF load, low-level output current of 8 mA, and high-level output current of -8 mA. It supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates six independent Schmitt-trigger inverters for noise filtering and signal conditioning
• Operates across a wide supply voltage range from 2 V to 5.5 V
• Provides robust output drive capability with 8 mA sink and source currents

Applications

• Signal conditioning for noisy digital environments
• Waveform shaping of slow-rise or slow-fall input signals
• Clock generation circuits requiring hysteresis

Procurement Notes

Verify the E4 suffix indicates lead-free construction and RoHS compliance per manufacturer specifications. Confirm the 14-TSSOP package dimensions match the target PCB footprint. Ensure the logic family compatibility aligns with system voltage levels before integration.

Selection Notes

Select this component when hysteresis is required to prevent false triggering on slow-moving signals. The AHC series offers faster performance than standard HC logic while maintaining CMOS compatibility. Verify that the 2 V minimum supply voltage meets the lowest system rail requirements.

Part Context

This part belongs to the SNx4AHC14 family of hex Schmitt-trigger inverters. It serves as a specialized logic gate variant designed for applications where input signal integrity is compromised by noise or slow transition times. The device complements other AHC series components like buffers and NAND gates.

Replacement Considerations
