SN74ALS32D

Overview

The SN74ALS32D is a quadruple 2-input positive-OR gate manufactured by Texas Instruments in the 74ALS logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device features four independent OR gates with push-pull outputs, providing a low-level output current of up to 8 mA and a high-level output current of -0.4 mA. Propagation delay times are specified between 3 ns and 16 ns under standard load conditions.

Feature Summary

• Contains four independent 2-input positive-OR gates performing Boolean functions Y = A + B
• Utilizes Advanced Low-Power Schottky (ALS) technology for optimized power-speed performance
• Provides push-pull outputs capable of driving moderate loads directly

Applications

• Digital logic circuits requiring Boolean OR operations
• Signal routing and selection networks
• Data bus management systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as the SOIC-14 housing requires careful handling during surface-mount assembly. Ensure compliance with RoHS directives if applicable to your specific manufacturing environment. Review datasheet specifications thoroughly before integration into final designs.

Selection Notes

Select this component when designing systems requiring fast switching speeds combined with low power consumption typical of ALS technology. Consider the 14-pin SOIC package constraints regarding board space and thermal dissipation. Evaluate whether the 8 mA sink capability meets downstream input requirements compared to standard LS series alternatives.

Part Context

This part belongs to the Texas Instruments 74ALS series, which bridges the performance gap between standard LS and AS families. The 'D' suffix specifically denotes the plastic small-outline integrated circuit package variant. This series is widely recognized for its reliability in commercial digital applications requiring efficient power usage without sacrificing significant speed.
