SN74LS14MR1

Inverter Gates Overview

The SN74LS14MR1 is a hex Schmitt-trigger inverter belonging to the Texas Instruments SN74LS series. It features six independent inverters with distinct positive and negative threshold voltages, enabling noise immunity for slow-rise signals. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a maximum propagation delay of 22 ns and output drive capabilities of -0.4 mA (low) and 8 mA (high). It utilizes TTL logic levels and is available in SOIC-14 packaging.

Inverter Gates Feature Summary

• Provides temperature-compensated hysteresis for clean signal regeneration
• Features enhanced line receiving characteristics for noisy environments
• Offers high noise immunity through distinct switching thresholds

Inverter Gates Applications

• Signal conditioning for slow-rising waveforms
• Noise filtering in digital communication lines
• Pulse generation from analog input signals

Inverter Gates Procurement Notes

Verify the manufacturer designation carefully, as the 'SN' prefix typically indicates Texas Instruments products rather than onsemi. Confirm that the specific MR1 suffix corresponds to the intended SOIC-14 package variant. Ensure compatibility with standard 5V TTL logic requirements before finalizing procurement orders.

Inverter Gates Selection Notes

Select this component when application requirements demand robust noise rejection for inputs with gradual transition times. The Schmitt trigger functionality is essential for stabilizing outputs against signal jitter. Verify that the low-power Schottky speed and current drive specifications align with the target circuit's timing and load constraints.

Inverter Gates Part Context

This component belongs to the widely adopted SN74LS family of logic integrated circuits. The LS designation signifies Low-power Schottky technology, which balances power consumption with switching speed. As a hex inverter, it serves as a fundamental building block for signal inversion and waveform shaping in digital systems.

Inverter Gates Replacement Considerations

Compatible substitutes include the SN74HC14 for CMOS applications or the SN74LVC14 for lower voltage operations. Verify pinout compatibility and ensure that the replacement device maintains the required Schmitt trigger hysteresis characteristics for the specific application.
