Overview
The SN7414NSR is a hex Schmitt-trigger inverter from Texas Instruments, part of the 74 logic family. It features six independent inverters with Schmitt-trigger inputs for noise immunity and improved line-receiving characteristics. The device operates within a supply voltage range of 4.75V to 5.25V. It provides a maximum low-level output current of 16 mA and a maximum high-level output current of -0.8 mA. The propagation delay is typically 22 ns at specified load conditions. It is housed in a 14-pin SOIC package (NS suffix) designed for surface-mount installation.
Feature Summary
- Hex Schmitt-trigger input configuration for enhanced noise immunity
- Improved line-receiving characteristics suitable for slow signal edges
- Standard TTL-compatible logic levels within specified voltage range
Applications
- HVAC gateway signal conditioning
- Waveform shaping for noisy digital signals
- Pulse generation from slowly changing input signals
Procurement Notes
Verify the package suffix 'NS' corresponds to the 14-lead Small Outline Package (SOIC) variant. Confirm the manufacturer is Texas Instruments to ensure compatibility with original datasheet specifications. Check RoHS compliance status if required by specific assembly standards. Ensure the component matches the intended surface-mount footprint requirements.
Selection Notes
Select this component when Schmitt-trigger action is required to clean up distorted or noisy digital signals. It is appropriate for applications involving slow-rise-time inputs where standard inverters might oscillate. Consider the 14-pin SOIC package for surface-mount PCB designs requiring compact integration of multiple inverter channels.
Part Context
This part belongs to the SN7414 series, which contains six Schmitt-trigger inverters. The 'NS' suffix denotes the 14-lead plastic small-outline package. It is a standard logic gate used for signal conditioning in digital circuits, distinct from non-Schmitt variants like the SN7404.
Replacement Considerations
Compatible substitutes include other hex Schmitt-trigger inverters such as the SN74LS14 or SN74HC14, provided voltage levels and drive currents meet circuit requirements. Verify pinout compatibility and electrical characteristics before substitution.
