SN74LS14NSR

Inverter Gates Overview

The SN74LS14NSR is a hex Schmitt-trigger inverter manufactured by Texas Instruments, belonging to the 74LS logic series. It features six independent inverters with Schmitt-trigger action for noise immunity and clean signal output from slowly changing waveforms. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports surface-mount installation in a 14-SOIC package. Key electrical characteristics include a maximum propagation delay of 22 ns at 5 V with 15 pF load capacitance, low-level output current of 8 mA, and high-level output current of 400 µA.

Inverter Gates Feature Summary

• Hex configuration providing six independent inverting channels within a single integrated circuit.
• Schmitt-trigger input action ensures distinct threshold voltages for rising and falling signals, enhancing noise rejection.
• Capable of converting very slow input transitions into sharp, well-defined digital output pulses without oscillation.
• Designed for robust performance in noisy environments or applications involving analog-to-digital conversion interfaces.

Inverter Gates Applications

• Signal conditioning for sensors producing slowly varying or noisy analog outputs.
• Clock waveform generation from non-ideal square waves.
• Pulse shaping in digital communication circuits.
• Debouncing mechanical switches in digital logic systems.

Inverter Gates Procurement Notes

Verify the specific suffix 'SR' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status as per the latest manufacturer documentation, noting that environmental classifications may vary by production batch. Ensure the supplier provides valid traceability data for the Texas Instruments manufacturing origin. Cross-reference the datasheet revision date to confirm compatibility with current design specifications before final procurement decisions.

Inverter Gates Selection Notes

Select this component when Schmitt-trigger functionality is required for hex inverter applications in surface-mount designs. Compare against standard 74LS14 variants based on packaging requirements, choosing the NSR suffix specifically for reel-based automated assembly processes. Evaluate propagation delay specifications against system timing constraints, noting the 22 ns limit under standard test conditions. Consider thermal management requirements given the operating temperature range and power dissipation characteristics inherent to the LS logic family.

Inverter Gates Part Context

This part belongs to the widely adopted 74LS (Low-power Schottky) logic family, known for balanced speed and power consumption. The SN74LS14 variant specifically integrates Schmitt triggers, distinguishing it from standard inverters like the SN74LS04. The 'NSR' designation identifies the surface-mount SOIC-14 package format supplied in a tape-and-reel configuration, suitable for high-volume manufacturing environments requiring consistent component handling and placement.

Inverter Gates Replacement Considerations

Direct pin-compatible substitutes include other manufacturers' SN74LS14 equivalents in SOIC-14 packages. Verify logical equivalence regarding Schmitt trigger thresholds and output drive capabilities. Alternative packages such as DIP-14 (SN74LS14N) offer functional parity but require different mounting strategies. Ensure any replacement maintains the same voltage range and propagation delay specifications to preserve circuit timing integrity.
