SN74ALS08D

Overview

The SN74ALS08D is a quadruple 2-input positive-AND gate from the Texas Instruments SN74ALS series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a SOIC-14 surface-mount package. Key electrical parameters include a propagation delay of 14 ns, a low-level output current of 8 mA, and a high-level output current of -400 µA. The device supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Contains four independent 2-input AND logic gates in a single integrated circuit
• Utilizes Advanced Low-Power Schottky (ALS) technology for optimized performance
• Provides standardized TTL-compatible input and output voltage levels

Applications

• Digital logic signal processing circuits
• Data acquisition systems requiring logical gating
• Industrial control logic interfaces

Procurement Notes

Verify the specific suffix 'D' confirms the SOIC-14 package variant during procurement. Confirm RoHS compliance status through official manufacturer documentation as requirements vary by region. Ensure the component meets the required industrial temperature specifications for the intended application environment before finalizing orders.

Selection Notes

Select this component when design requirements specify the ALS logic family characteristics. Verify that the 14 ns propagation delay aligns with system timing constraints. Ensure the power supply voltage remains strictly between 4.5 V and 5.5 V to maintain correct logic level operation and prevent device malfunction.

Part Context

This part belongs to the SN74ALS08 family, which provides quad 2-input AND gates. The 'ALS' designation indicates Advanced Low-Power Schottky technology, offering a balance between speed and power consumption compared to standard or other variants within the broader 74xx logic ecosystem.

Replacement Considerations

SN74ALS08DR: Identical functional logic but supplied in tape-and-reel packaging instead of tubes.
