SN74LS14DG4

Inverter Gates Overview

The SN74LS14DG4 is a hex Schmitt-trigger inverter manufactured by Texas Instruments, belonging to the LS logic series. It features six independent inverters with Schmitt-trigger inputs for noise filtering and waveform shaping. The device operates within a supply voltage range of 4.75V to 5.25V. It utilizes a 14-pin Small Outline Integrated Circuit (SOIC) package designed for surface-mount applications. The component supports an operating temperature range from 0°C to 70°C.

Inverter Gates Feature Summary

• Integrates six independent Schmitt-trigger inverters for signal conditioning
• Provides hysteresis to filter noise and shape slow-rise/fall-time waveforms
• Compatible with standard TTL logic levels in the LS series family

Inverter Gates Applications

• Signal conditioning for noisy digital environments
• Waveform shaping for oscillators and pulse generators
• Transitioning slow input signals to clean digital logic levels

Inverter Gates Procurement Notes

Verify the complete part number including the G suffix to confirm RoHS compliance status. Confirm the SOIC-14 package variant matches design constraints. Ensure the LS logic family specifications align with system power and speed requirements before procurement.

Inverter Gates Selection Notes

Select this component when Schmitt-trigger functionality is required within a standard TTL-compatible environment. The LS series offers lower power consumption compared to standard TTL while maintaining compatible logic levels. Verify that the surface-mount SOIC package fits the board layout and thermal management strategy.

Inverter Gates Part Context

This part belongs to the Texas Instruments SN74xxLS family, which provides low-power Schottky logic performance. The SN74LS14 specifically adds Schmitt-trigger inputs to the standard inverter function, distinguishing it from non-Schmitt variants like the SN74LS04. It serves as a key component for interface circuits requiring noise immunity.
