SN74AHCT08MDREP

Overview

The SN74AHCT08MDREP is a quad 2-input AND gate manufactured by Texas Instruments, belonging to the 74AHCT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features CMOS input/output types. The device provides a low-level output current of 8 mA and a high-level output current of -8 mA. Propagation delay is specified at 7.9 ns when driven at 5 V with a 50 pF load. It is housed in a 14-SOIC package (0.154 inch width) and supports surface mount installation. The component functions reliably across an operating temperature range from -55°C to +125°C.

Feature Summary

• Contains four independent 2-input AND gates for complex logic implementation
• Compatible with standard 5 V CMOS logic families due to AHCT architecture
• Supports wide industrial temperature operation for harsh environments

Applications

• Digital signal processing circuits requiring logical conjunction operations
• Data routing systems utilizing multiple parallel logic channels
• Industrial control interfaces operating under extended thermal conditions

Procurement Notes

Verify the specific suffix MDREP against official Texas Instruments documentation to confirm the SOIC-14 package variant and mil-enhanced manufacturing status. Ensure compatibility with existing board layouts regarding pin assignments and thermal dissipation requirements. Cross-reference the datasheet revision history to validate electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when designing systems that require precise timing synchronization between multiple digital signals using standard 5 V logic levels. The AHCT series ensures seamless integration with older TTL-compatible designs while offering improved noise immunity. Consider the 14-pin SOIC footprint constraints and verify that the 8 mA drive capability meets the downstream load requirements without exceeding power dissipation limits.

Part Context

This part belongs to the broader SN74AHCT family of high-speed CMOS logic devices produced by Texas Instruments. The AHCT designation indicates compatibility with 5 V CMOS inputs while maintaining performance metrics suitable for modern digital applications. The SN74AHC00MPWREP serves as a related NAND gate alternative within the same manufacturer portfolio, sharing similar operational voltages but differing in logical function.

Replacement Considerations

Publicly confirmed substitute part numbers include MC74VHCT08ADR2G, MC74VHCT08ADTR2G, 74AHCT08D,118, and 74AHCT08S14-13.
