SN74AHC14DBR

Overview

The SN74AHC14DBR 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 supports CMOS input logic levels. The device contains six independent inverting circuits, each featuring Schmitt-trigger inputs for noise filtering. It provides high-level output currents of -8 mA and low-level output currents of 8 mA. The component functions reliably across an operating temperature range from -40°C to +125°C. It is housed in a 14-pin SOIC surface-mount package.

Feature Summary

• Hex configuration with six independent Schmitt-trigger inverters
• Wide operating voltage range supporting 2 V to 5.5 V supplies
• Schmitt-trigger inputs provide noise filtering and hysteresis
• High drive capability with 8 mA output current sourcing and sinking

Applications

• Signal conditioning for noisy digital environments
• Waveform shaping and pulse generation
• Oscillator circuits requiring precise threshold control
• Level shifting between different voltage domains

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements if mandated by your design standards. Cross-reference the datasheet revision date to confirm technical parameters match your application needs before finalizing procurement decisions.

Selection Notes

Select this component when multiple inverted signals with noise immunity are required in a single package. The AHC series offers faster switching speeds compared to standard 74HC devices while maintaining low power consumption. Verify that the 14-pin SOIC footprint aligns with your PCB layout constraints and that the 2 V to 5.5 V voltage range covers your system's operational limits.

Part Context

This part belongs to the SN74AHC14 family of hex Schmitt-trigger inverters. It shares functional similarities with other variants like the SN74AHC14DR but differs in packaging and reel specifications. The device is designed for general-purpose digital applications requiring robust signal integrity and wide voltage compatibility within the CMOS logic family.

Replacement Considerations

The SN74AHC14DR is a direct pin-to-pin replacement offering identical electrical characteristics and functionality. Both parts belong to the same logical family and can be interchanged without circuit modification.
