SN74AHCT00DBR

Overview

The SN74AHCT00DBR is a single-function logic gate manufactured by Texas Instruments, featuring four independent 2-input NAND gates. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL-compatible inputs with CMOS outputs. The device provides an output current capability of 8 mA for both high and low states. It exhibits a propagation delay of 9 ns and functions reliably across an operating temperature range from -40°C to +85°C. Packaged in a 14-pin SSOP format, it draws a typical working power supply current of 20 µA.

Feature Summary

• Integrates four independent 2-input NAND logic gates within a single package
• Ensures compatibility with TTL input levels while providing CMOS output characteristics
• Delivers robust 8 mA drive capability for both high and low output states

Applications

• Digital signal processing circuits requiring NAND logic operations
• Microcontroller interface designs utilizing TTL-to-CMOS level translation
• General-purpose logic control systems in consumer electronics

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the part number with the latest datasheet revisions to confirm compliance with current RoHS standards and environmental regulations before finalizing purchase orders.

Selection Notes

Select this component when a design requires multiple NAND gates with TTL-compatible input thresholds in a compact surface-mount package. It is suitable for applications operating strictly at 5 V where moderate speed and standard drive strength are sufficient. Consider alternative series if wider voltage ranges or lower power consumption are required, as this device is optimized for 5 V operation.

Part Context

This component belongs to the SN74AHCT00 series, which combines the high-speed performance of Advanced CMOS technology with TTL-compatible inputs. The 'D' suffix indicates the SSOP-14 package style, while the 'BR' suffix typically denotes reel packaging. This series is designed for general-purpose digital applications requiring reliable logic switching in industrial and commercial environments.

Replacement Considerations

Direct functional substitutes include other quad 2-input NAND gates from the same family, such as the SN74AHCT00DR. Verify pinout compatibility and electrical parameters against the original datasheet before substitution.
