SN74HCT14DRE4

Inverter Gates Overview

The SN74HCT14DRE4 is a hex Schmitt-trigger inverter manufactured by Texas Instruments, belonging to the HCT logic family. It features six independent inverters with Schmitt-trigger inputs for noise filtering and waveform shaping. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL-compatible input levels. It provides standard CMOS outputs with a high-level output current of -4 mA and a low-level output current of 4 mA. The component is housed in a 14-pin SOIC package and is designed for surface-mount installation.

Inverter Gates Feature Summary

• Hex configuration containing six independent Schmitt-trigger inverters
• Schmitt-trigger action at all inputs ensures clean signal transitions from noisy or slowly rising edges
• TTL-compatible input logic levels allow direct interfacing with TTL sources
• CMOS output structure provides standard drive capabilities

Inverter Gates Applications

• Waveform shaping of digital signals
• Noise elimination in digital circuits
• Pulse generation applications
• Transition detection systems

Inverter Gates Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the package type matches the required 14-SOIC footprint. Ensure the operating temperature range aligns with system requirements. Cross-reference the datasheet revision to confirm pinout consistency. Validate that the component meets the necessary environmental certifications for the intended deployment.

Inverter Gates Selection Notes

Select this component when TTL-compatible logic levels are required alongside the noise immunity provided by Schmitt triggers. It serves as a suitable alternative to HC series devices where faster switching speeds are not critical but robust input thresholds are necessary. Consider the 14-SOIC package constraints for PCB layout. Evaluate the propagation delay specifications against the maximum clock frequency of the application circuit.

Inverter Gates Part Context

This part belongs to the SN74HCT14 family of hex Schmitt-trigger inverters. The 'D' suffix denotes the 14-pin SOIC package variant. The 'R' indicates reel packaging, while 'E4' signifies lead-free construction compliant with RoHS directives. This family is widely used in general-purpose digital logic applications requiring signal conditioning.

Inverter Gates Replacement Considerations

Compatible substitutes include the SN74HCT14DR and SN74HCT14N. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement part maintains the same HCT logic family specifications.
