SN74ALS10AD

Overview

The SN74ALS10AD is a Texas Instruments logic gate belonging to the Advanced Low-Power Schottky (ALS) family. It contains three independent 3-input positive-NAND gates housed in a 14-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from 0°C to +70°C. Key electrical specifications include a propagation delay of 11 ns, a low-level output current capability of 8 mA, and a high-level output current of -400 uA.

Feature Summary

• Integrates three independent 3-input NAND logic functions within a single integrated circuit.
• Utilizes Advanced Low-Power Schottky technology to achieve faster switching speeds compared to standard LS series devices while maintaining reduced power consumption.
• Features push-pull outputs capable of driving standard TTL loads with defined high and low state current capabilities.

Applications

• Digital signal processing circuits requiring fast logical inversion
• Microprocessor-based system address decoding
• General-purpose combinatorial logic implementation

Procurement Notes

Verify the specific suffix 'AD' confirms the SOIC-14 surface-mount package variant rather than the through-hole DIP version. Confirm RoHS compliance status as required by project specifications. Ensure the ordering quantity aligns with the manufacturer's tube packaging configuration for this specific package type.

Selection Notes

Select this component when design requirements demand higher speed performance than standard LS logic but lower cost than AS series devices. The ALS family offers a balanced trade-off between power dissipation and propagation delay suitable for general digital applications. Verify that the 14-pin SOIC footprint matches the target PCB layout constraints.

Part Context

This part belongs to the widely adopted 74-series logic family, specifically the Advanced Low-Power Schottky subset. It serves as a direct functional equivalent to other 3-input NAND gates within the ecosystem, providing standardized pinouts and electrical characteristics compatible with existing TTL designs.

Replacement Considerations

SN74ALS10N: Through-hole PDIP-14 equivalent with identical logic function and electrical parameters.
