SN74LS384N

Overview

The SN74LS384N is an 8-bit by 1-bit two's complement multiplier belonging to the Texas Instruments LS series. It operates within a supply voltage range of 4.75 V to 5.25 V and functions at temperatures from 0°C to +70°C. The component utilizes a 16-pin PDIP package and exhibits propagation delays between 3.4 ns and 5.6 ns.

Feature Summary

• Performs 8-bit by 1-bit two's complement multiplication
• Compatible with standard TTL logic families

Applications

• Digital signal processing systems requiring fixed-point arithmetic
• Embedded control units performing integer multiplication
• Industrial automation controllers using TTL-based architectures

Procurement Notes

Verify RoHS compliance status as the SN74LS384N is classified as non-compliant. Confirm lead times for obsolete or end-of-life inventory through authorized distributors. Ensure storage conditions respect the Moisture Sensitivity Level (MSL) rating of 3, which allows 168 hours of floor life before reflow soldering is required.

Selection Notes

Select this component only when legacy TTL compatibility is mandatory. Evaluate power dissipation requirements due to LS series characteristics. Consider modern CMOS alternatives if lower power consumption or wider voltage ranges are necessary for the target application design.

Part Context

This device belongs to the Texas Instruments 74LS logic family, designed for high-speed digital applications using standard transistor-transistor logic technology. The SN74LS384N specifically addresses arithmetic operations within this ecosystem, providing dedicated hardware acceleration for multiplication tasks in older digital systems.

Replacement Considerations

No public confirmed substitute part numbers are available.
