SN74HC14AN

Inverter Gates Overview

The SN74HC14AN is a hex Schmitt-trigger inverter from the Texas Instruments 74HC logic family. It integrates six independent inverters within a single 14-pin Dual In-Line Package (PDIP). The device operates on a supply voltage range of 2V to 6V and supports input levels down to 0.3V at low states. It features high noise immunity due to Schmitt-trigger inputs, which provide distinct threshold voltages for rising and falling signals. The component is rated for operation across an extended temperature range of -40°C to 85°C.

Inverter Gates Feature Summary

• Integrates six independent inverting channels with Schmitt-trigger inputs for signal conditioning
• Provides high noise immunity through defined hysteresis thresholds
• Compatible with standard CMOS logic families including TTL-driven outputs

Inverter Gates Applications

• Signal wave shaping and pulse generation
• Oscillator circuits requiring stable frequency generation
• Noise filtering for digital input lines

Inverter Gates Procurement Notes

Verify the package type matches the required DIP-14 configuration. Confirm the suffix 'A' indicates the specific manufacturing revision. Ensure the operating environment stays within the specified temperature limits. Check RoHS compliance status against current regulatory requirements. Validate pinout compatibility with existing PCB footprints before integration.

Inverter Gates Selection Notes

Select this component when noise immunity is critical for digital signal integrity. The Schmitt-trigger feature distinguishes it from standard inverters like the SN74HC04. Consider the PDIP package for through-hole prototyping or applications requiring manual assembly. Evaluate power consumption constraints as HC series devices offer low static current draw compared to older logic families.

Inverter Gates Part Context

This part belongs to the widely adopted 74HC series of high-speed CMOS logic devices. It serves as a fundamental building block for digital logic design, providing reliable inversion capabilities. The SN74HC14 variant specifically addresses scenarios where input signals are slow or noisy, ensuring clean transitions between logic states without false triggering.
