DM7402N

Inverter Gates Overview

The DM7402N is a quad 2-input NOR gate integrated circuit manufactured by onsemi, originally produced by Fairchild Semiconductor. It operates within a supply voltage range of 4.75V to 5.25V and features four independent logic gates in a 14-lead plastic dual-in-line package (PDIP). The device supports standard TTL logic levels with a high-level input voltage minimum of 2V and a low-level input voltage maximum of 0.8V. Electrical characteristics include a low-level output current capability of 16mA and propagation delays of 22ns for LOW-to-HIGH transitions and 15ns for HIGH-to-LOW transitions at VCC = 5V.

Inverter Gates Procurement Notes

Verify the component status as this part may be obsolete or superseded by newer equivalents. Confirm that the 14-pin PDIP package matches your board layout requirements. Ensure the operating temperature range of 0°C to +70°C meets your environmental specifications. Check RoHS compliance status if required for modern manufacturing standards. Validate pinout compatibility with existing designs before procurement.

Inverter Gates Selection Notes

Select this component when a quad NOR gate configuration is required for digital logic applications. Consider the 16mA low-level output current for driving moderate loads. Verify that the 22ns propagation delay is acceptable for your signal timing requirements. Ensure the 14-PDIP package fits your assembly process. Compare against other 74-series logic families if lower power consumption or higher speed is needed.

Inverter Gates Part Context

This device belongs to the 7400-series standard logic family, specifically the NOR gate category. It was originally developed by Fairchild Semiconductor and is now part of onsemi's portfolio. The DM7402N provides a reliable solution for implementing basic Boolean logic functions in digital circuits. It serves as a fundamental building block for more complex combinational logic designs.

Inverter Gates Replacement Considerations

Direct substitutes include SN7402N from Texas Instruments. Verify pinout and electrical parameter compatibility before substitution. Check for updated packaging options or lead-free variants if required by current manufacturing standards.
