Inverter Gates datasheet and documents for SN74LS14D
Inverter Gates Overview
The SN74LS14D is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It contains six independent inverters within a single package. The device operates with a supply voltage range of 4.75 V to 5.25 V. It features distinct positive-going and negative-going threshold voltages, enabling the conversion of slowly changing signals into clean digital outputs. The maximum propagation delay is specified at 22 ns under standard test conditions.
Inverter Gates Feature Summary
- Incorporates Schmitt-trigger action for hysteresis
- Converts slow input transitions to sharp output edges
- Provides temperature-compensated threshold levels
Inverter Gates Applications
- Signal conditioning for noisy environments
- Waveform shaping from analog inputs
- Pulse generation circuits
Inverter Gates Procurement Notes
Verify the specific suffix 'D' indicates the SOIC-14 surface-mount package configuration. Confirm the logic family designation 'LS' aligns with Low-power Schottky TTL requirements. Ensure the manufacturer source is Texas Instruments or an authorized distributor to guarantee component authenticity and datasheet accuracy.
Inverter Gates Selection Notes
Select this component when hysteresis is required to prevent output oscillation during signal transitions. The LS series offers a balance between power consumption and speed suitable for general-purpose digital logic applications. Verify that the operating voltage remains within the 4.75 V to 5.25 V range for proper functionality.
Inverter Gates Part Context
This part belongs to the 74LS logic family, which utilizes Low-power Schottky technology. The '14' designation specifically identifies the hex inverter function with Schmitt triggers. The 'SN' prefix denotes commercial grade temperature operation. This series is widely used in legacy and modern digital systems requiring noise immunity.
Inverter Gates Replacement Considerations
Compatible substitutes include SN74LS14N (PDIP package) and SN74LS14NSR (tape and reel). Cross-family replacements like SN74HC14 or SN74HCT14 require voltage level verification.
