SN7400DG4

Overview

The SN7400DG4 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 11 ns at 5 V with 15 pF load capacitance. 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
• Standard TTL logic levels ensure compatibility with existing digital systems
• Surface-mount SOIC-14 package facilitates automated PCB assembly

Applications

• Digital logic circuit design
• Microprocessor system interfacing
• General-purpose switching applications

Procurement Notes

Verify the suffix 'G4' indicates RoHS compliance and lead-free construction per manufacturer specifications. Confirm the package type matches the required SOIC-14 footprint. Ensure the operating temperature range meets the specific environmental requirements of the target application before finalizing procurement.

Selection Notes

Select this component when standard TTL performance is required for general-purpose logic functions. The SN7400DG4 offers a balance of speed and drive capability suitable for most digital applications. Consider the 14-pin SOIC package for space-constrained designs requiring surface-mount technology.

Part Context

This part belongs to the SN7400 family of quadruple 2-input NAND gates. It is a variant of the standard SN7400 series, distinguished by its RoHS-compliant manufacturing process and specific packaging configuration. The device serves as a fundamental building block for digital electronics.

Replacement Considerations

Compatible substitutes include SN7400D and SN7400DR. Verify pinout and electrical characteristics match before substitution.
