SN7400DRE4

Overview

The SN7400DRE4 is a quadruple 2-input positive-NAND gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features a propagation delay of 22 ns at 5 V with 15 pF load. The device provides a low-level output current of 16 mA and a high-level output current of -400 µA. It is housed in a 14-SOIC surface-mount package and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Contains four independent NAND gates for complex logic implementation
• Compatible with standard CMOS logic families via HCT input structures
• Provides robust low-level sink current capability

Applications

• Digital signal processing logic circuits
• Microcontroller interface gating
• Memory address decoding

Procurement Notes

Verify the suffix 'E4' indicates lead-free composition and RoHS compliance. Confirm the 'DR' designation corresponds to the SOIC-14 package type. Ensure the ordering code matches the specific reel quantity requirements for automated assembly processes.

Selection Notes

Select this component when standard TTL-compatible NAND functionality is required in a surface-mount design. It serves as a direct replacement for through-hole DIP variants in space-constrained PCB layouts while maintaining identical logical performance characteristics.

Part Context

This part belongs to the SN7400 family of basic logic gates. It implements the fundamental NAND operation, serving as a building block for more complex digital systems such as flip-flops, counters, and shift registers within industrial and consumer electronic applications.
