SN74AHC08MDREP

Overview

The SN74AHC08MDREP is a quad 2-input positive AND gate manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features low dynamic power consumption. The device provides an output current capability of 8 mA at both high and low logic levels. Propagation delay is specified at 9 ns. It supports an operating temperature range from -55 °C to +125 °C and utilizes a 14-SOIC surface-mount package.

Feature Summary

• Provides four independent 2-input AND logic functions in a single integrated circuit
• Operates across a wide supply voltage range from 2 V to 5.5 V for flexible system integration
• Features low dynamic power consumption suitable for battery-powered applications
• Supports hot insertion with current overrating capabilities

Applications

• Portable consumer electronics requiring low power operation
• Battery-powered systems utilizing wide voltage ranges
• Computing equipment and peripheral interfaces
• Telecommunications infrastructure components

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type, tape-and-reel specifications, and environmental compliance status. Ensure the component matches the required logic family and pinout configuration for your design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when designing circuits that require multiple AND gates within a compact SOIC-14 footprint. It is appropriate for applications needing operation below 3.3 V down to 2 V, distinguishing it from standard 5 V-only logic families. Consider its propagation delay and drive strength relative to signal integrity requirements in high-speed digital designs.

Part Context

This component belongs to the SN74AHC08 series of high-speed CMOS logic gates. It is part of Texas Instruments' broader portfolio of AHC (Advanced High-Speed CMOS) devices designed for performance optimization. The series offers compatibility with standard TTL inputs while providing improved switching speeds and lower power dissipation compared to legacy logic families.

Replacement Considerations

Direct substitutes include the SN74AHC08D and SN74AHC08DR from Texas Instruments, which share identical logical functionality and pin configurations. Other compatible alternatives may include equivalent parts from manufacturers such as Nexperia or ON Semiconductor, provided they meet the same voltage, speed, and package specifications.
