SN74LS14NE4

Inverter Gates Overview

The SN74LS14NE4 is a hex Schmitt-trigger inverter from the Texas Instruments 74LS series, housed in a 14-pin PDIP package. It operates within a supply voltage range of 4.75V to 5.25V and supports a commercial temperature range of 0°C to 70°C. The device features six independent inverters with Schmitt-trigger inputs for noise immunity. Key electrical parameters include a maximum propagation delay of 22ns at 5V with 15pF load, low-level output current of 8mA, and high-level output current of -400µA.

Inverter Gates Feature Summary

• Hex Schmitt-trigger architecture provides hysteresis for improved noise immunity on input signals
• Six independent inverting channels integrated into a single 14-pin DIP package
• Compatible with standard 5V logic systems within specified voltage tolerances

Inverter Gates Applications

• Signal conditioning for noisy digital environments requiring clean transitions
• Waveform shaping and pulse generation circuits
• Oscillator and timing circuit implementations

Inverter Gates Procurement Notes

Verify the NE4 suffix indicates lead-free compliance and RoHS status against the latest manufacturer datasheet. Confirm the PDIP-14 package dimensions match design requirements. Ensure the component meets the specified commercial temperature range for the intended application environment.

Inverter Gates Selection Notes

Select this component when Schmitt-trigger action is required for signal integrity rather than standard logic inversion. Compare propagation delays and output drive capabilities against other 74LS variants if speed or load requirements differ. Verify package availability and pin compatibility during PCB layout finalization.

Inverter Gates Part Context

This part belongs to the Texas Instruments 74LS (Low-power Schottky) family, known for balanced speed and power consumption. The SN74LS14 variant specifically adds Schmitt-trigger functionality compared to the standard SN74LS04 inverter, making it suitable for interfaces with slow-rising or noisy signals.

Inverter Gates Replacement Considerations

SN74LS14N serves as the standard non-leaded equivalent. SN74LS14NSR offers the same function in a surface-mount SOIC package. Cross-reference with other manufacturers' 74LS14 equivalents ensuring identical pinouts and electrical specifications.
