SN74AC00DBR

Overview

The SN74AC00DBR is a Texas Instruments quadruple 2-input positive-NAND gate in the AC logic family. It operates on a supply voltage (VCC) of 2V to 6V and features inputs that accept voltages up to 6V. The device provides a maximum propagation delay (tpd) of 7ns at 5V. It utilizes a 14-pin SSOP package with a body size of 5mm x 6.4mm. The component supports an operating free-air temperature range from -40°C to +85°C.

Feature Summary

• Contains four independent 2-input NAND gates performing Boolean functions
• Operates across a wide supply voltage range from 2V to 6V
• Inputs tolerate voltages up to 6V for flexible interfacing

Applications

• Digital logic circuit design requiring NAND functionality
• Signal processing systems utilizing CMOS technology
• General-purpose electronic equipment using standard logic families

Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the SSOP-14 package and tape-and-reel carrier configuration. Confirm the manufacturer part number matches the official datasheet SCAS524G revision. Ensure the component meets the required RoHS compliance standards and lead finish specifications for your assembly process.

Selection Notes

Select this component when a high-speed AC logic NAND gate is required within a 2V to 6V operating range. The SSOP-14 package offers a compact surface-mount solution suitable for space-constrained designs. Consider the 7ns propagation delay at 5V for timing-critical applications compared to slower HC series alternatives.
