SN74AC08NS

Overview

The SN74AC08NS is a quadruple 2-input positive-AND gate manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and supports an input voltage up to 6V. The device features a maximum propagation delay of 7.5ns at 5V. It provides high-level output currents of -12mA at 3V and -24mA at 4.5V or 5.5V, with low-level output currents of 12mA at 3V and 24mA at 4.5V or 5.5V. The component is housed in a 14-pin Small Outline (NS) package and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Performs Boolean AND logic function Y = A • B

Applications

• Digital logic circuits
• LED drivers
• Digital signal processing
• Control and automation systems

Procurement Notes

Verify the specific ordering suffix 'NS' corresponds to the 14-pin Small Outline package. Confirm RoHS compliance status and lead finish details via the manufacturer's current packaging addendum. Ensure the operating temperature range meets system requirements before procurement.

Selection Notes

Select this component for designs requiring quad 2-input AND gates with CMOS performance characteristics. Consider the 14-pin SOP package for surface-mount applications. Verify that the 2V to 6V supply range aligns with the system power architecture.

Part Context

This part belongs to the SNx4AC08 family of quadruple 2-input positive-AND gates. The AC series offers higher speed and wider voltage operation compared to standard TTL or HC families. The NS suffix specifically denotes the small outline package variant within the catalog.

FAQ

What is the maximum propagation delay?

The maximum propagation delay is 7.5ns when operating at 5V.

Can unused inputs be left floating?

No, all unused inputs must be tied to VCC or GND to prevent undefined operational states.
