SN74HCT14D

Inverter Gates Overview

The SN74HCT14D is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It belongs to the HCT logic series and utilizes CMOS technology. The device contains six independent inverters within a single package. It operates with a supply voltage range of 4.5 V to 5.5 V. The component is housed in a 14-pin SOIC surface-mount package. It supports a minimum operating temperature of -40°C and a maximum of +85°C. The typical propagation delay is 38 ns. Output drive capabilities include 4 mA for both high and low states.

Inverter Gates Feature Summary

• Integrates six independent Schmitt-trigger inverters for signal conditioning
• Provides noise immunity through defined input hysteresis thresholds
• Compatible with standard TTL logic levels via HCT architecture
• Designed for surface-mount assembly in compact electronic circuits

Inverter Gates Applications

• Signal wave shaping from noisy or slow-rise inputs
• Pulse generation and timing circuit applications
• Oscillator circuits requiring stable switching thresholds
• Level shifting between different logic families

Inverter Gates Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the ordering suffix matches the required package type and tape-and-reel specifications. Check RoHS compliance status and moisture sensitivity level requirements before integration into the manufacturing process. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Inverter Gates Selection Notes

Select this component when interfacing with systems requiring 5 V operation and TTL-compatible input thresholds. The HCT series ensures compatibility with older digital logic standards while offering modern CMOS power efficiency. Consider the SOIC-14 package dimensions for PCB layout constraints. Evaluate the propagation delay characteristics against the system's maximum clock frequency requirements to ensure signal integrity.

Inverter Gates Part Context

This device is part of the broader SN74HCT14 family, which includes various packaging options such as TSSOP and DIP variants. The D suffix specifically denotes the SOIC-14 surface-mount package configuration. It serves as a fundamental building block in digital electronics for converting analog-like signals into clean digital pulses. The family shares core electrical characteristics but differs in physical footprint and mounting style.

Inverter Gates Replacement Considerations

Cross-reference with other manufacturers' 74HCT14 equivalents if supply chain constraints exist. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure the alternative component meets the same voltage and temperature specifications.
