SN74LS14NS

Inverter Gates Overview

The SN74LS14NS is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within the LS logic family and features six independent inverters with Schmitt-trigger inputs, providing hysteresis for noise immunity. The device is housed in a 14-pin SOIC surface-mount package. It supports a supply voltage range of 4.75V to 5.25V. Key electrical characteristics include a maximum propagation delay of 22ns at 5V with a 15pF load, a high-level output current of -400µA, and a low-level output current of 8mA. The operating temperature range is specified from 0°C to 70°C.

• Oscillator circuits

Inverter Gates Procurement Notes

Verify the specific suffix 'NS' confirms the SOIC-14 surface-mount package variant rather than the PDIP through-hole version. Confirm RoHS compliance status as manufacturing updates may affect material declarations. Ensure the supplier provides valid traceability documentation for the Texas Instruments manufacturer part number.

Inverter Gates Selection Notes

Select this component when Schmitt-trigger action is required to clean noisy digital signals or convert slow-rising waveforms into sharp transitions. The LS series offers standard TTL compatibility with lower power consumption compared to standard 74S series devices. Verify that the SOIC package fits the PCB layout constraints and thermal requirements of the design.

Inverter Gates Part Context

This part belongs to the Texas Instruments 74LS14 family of hex Schmitt-trigger inverters. The 'N' suffix typically denotes the DIP package, while 'NS' specifically identifies the SOIC surface-mount variant. These devices are widely used in digital systems requiring robust input stages for timing applications.

Inverter Gates FAQ

What is the primary function of the Schmitt trigger inputs?

The Schmitt trigger inputs provide hysteresis, allowing the device to accept very slow input transition times and produce crisp, noise-immune output transitions.

How does the SN74LS14NS differ from the SN74LS14N?

The SN74LS14NS uses an SOIC surface-mount package, whereas the SN74LS14N uses a PDIP through-hole package. Both contain the same internal circuitry.
