SN74HCT14PWRE4

Inverter Gates Overview

The SN74HCT14PWRE4 is a hex Schmitt-trigger inverter from Texas Instruments, belonging to the HCT logic series. It features six independent inverters with Schmitt-trigger inputs for noise immunity and clean signal transitions. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 14-pin TSSOP surface-mount package. It supports an operating temperature range from -40°C to +85°C.

Inverter Gates Feature Summary

• Hex configuration providing six independent inverting channels
• Schmitt-trigger input architecture ensures stable switching with hysteresis
• CMOS output structure compatible with standard TTL logic levels

Inverter Gates Applications

• Signal conditioning for noisy digital environments
• Waveform shaping and pulse generation circuits
• Transitioning slow-rise/fall-time signals into sharp digital edges

Inverter Gates Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the TSSOP-14 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your system's environmental specifications before finalizing procurement.

Inverter Gates Selection Notes

Select this component when multiple inverted outputs are required in a compact surface-mount form factor. The HCT series ensures compatibility with 5V CMOS systems while offering improved noise margins compared to standard non-Schmitt inverters. Consider the propagation delay characteristics relative to your maximum clock frequency requirements.

Inverter Gates Part Context

This part belongs to the widely used 74HCT logic family, designed for high-speed CMOS applications with TTL-compatible inputs. The 'SN' prefix denotes commercial grade temperature range, while 'PW' specifies the TSSOP package type. The 'E4' suffix typically identifies lead-free manufacturing processes compliant with international environmental directives.

Inverter Gates FAQ

What is the primary benefit of the Schmitt-trigger input?

It provides hysteresis, which prevents output oscillation caused by noise or slow-rising input signals, ensuring clean digital transitions.

Is this component suitable for automotive applications?

No, the SN74HCT14PWRE4 is rated for a commercial temperature range (-40°C to +85°C). Automotive-grade versions typically carry a 'Q1' suffix and wider temperature ratings.
