SN74AS08NS

Overview

The SN74AS08NS is a Texas Instruments SN74AS08 device featuring four independent 2-input positive-AND gates in a 14-pin SOP (NS) package. 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 component provides a low-level output current of 20 mA and a high-level output current of -2 mA. Propagation delay times are specified with maximum values of 5.5 ns for both tPLH and tPHL transitions under standard load conditions.

Feature Summary

• Contains four independent 2-input positive-AND logic gates
• Supports operation across the commercial temperature range of 0°C to 70°C
• Provides robust low-level output drive capability

Applications

• Boolean logic implementation using Y = A • B functions
• Digital signal processing circuits requiring fast switching speeds
• General-purpose logic gate integration in electronic systems

Procurement Notes

Verify that the specific ordering suffix 'NS' corresponds to the Small Outline Package (SOP) variant when sourcing components. Confirm the manufacturer designation matches Texas Instruments specifications. Ensure compatibility with the required 14-pin footprint and verify RoHS compliance status against current product documentation before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high-speed AND logic operations within standard commercial temperature limits. Compare propagation delays and output drive currents against system requirements. Evaluate the SOP package dimensions against available board space constraints. Consider alternative series such as ALS if lower power consumption is prioritized over speed.

Part Context

This part belongs to the SN74AS08 family, which utilizes Advanced Schottky technology to achieve faster switching speeds compared to standard TTL logic families. The device integrates four separate AND gates into a single integrated circuit, providing a compact solution for complex digital logic designs requiring multiple independent logic functions.

Replacement Considerations

SN74AS08DR serves as a parameter-equivalent replacement offering identical electrical characteristics in a SOIC package format.
