SN74AS131AD

Overview

The SN74AS131AD is a monostable multivibrator from the Texas Instruments AS logic family, housed in a 16-pin SOIC surface-mount package. It operates on a single supply voltage ranging from 4.5 V to 5.5 V and supports data rates up to 125 Mbps. The device features an ultra-high speed performance with an average propagation delay of less than 5 ns. It includes a master reset input for controlling output pulse width and is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Ultra-high-speed operation supporting data rates up to 125 Mbps
• Master reset input allows control over output pulse width
• Single-supply operation within the standard 4.5 V to 5.5 V range

Applications

• Pulse generation circuits
• Timing delays
• Waveform shaping

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official documentation to confirm the exact temperature rating and electrical characteristics. Ensure the SOIC-16 package dimensions match the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when high-speed monostable functionality is required within the AS logic family. Consider the 16-pin SOIC package for surface-mount assembly needs. Verify that the 4.5 V to 5.5 V supply range aligns with the system power architecture.
