SN74AC08D

Overview

The SN74AC08D is a quad 2-input AND gate integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and features low static current consumption of 2 µA maximum. The device provides symmetrical output drive capabilities with both high and low level output currents rated at 24mA. Propagation delay is specified at 7.5ns when tested at 5V with a 50pF load. It is housed in a 14-SOIC surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides four independent 2-input AND logic functions within a single package
• Features symmetrical output drive strength for consistent signal integrity
• Operates across a wide DC supply voltage range from 2V to 6V
• Maintains low quiescent current consumption for power efficiency

Applications

• Digital logic data processing circuits
• Signal gating and masking operations
• General-purpose digital systems requiring fast switching speeds

Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to confirm pinout compatibility and electrical specifications. Ensure the selected component meets the required operating temperature range and supply voltage constraints for the target application environment before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring fast propagation delays and robust output drive capabilities compared to standard logic families. Consider the 14-SOIC package dimensions for PCB layout constraints. Verify that the 2V to 6V supply range aligns with the system's power architecture and that the -40°C to +85°C industrial temperature rating satisfies environmental requirements.

Part Context

This device belongs to the SN74AC series, representing advanced CMOS technology from Texas Instruments. It offers significantly faster switching speeds than standard 74HC counterparts while maintaining low power consumption. The SN74AC08D serves as a fundamental building block for complex digital logic designs requiring reliable AND functionality with high-speed performance characteristics.

Replacement Considerations

SN74AC08DR: Identical logical function and electrical specifications; differs only in tape-and-reel packaging format instead of tube packaging.
