MM74HC02MX

Inverter Gates Overview

The MM74HC02MX is a quad 2-input NOR gate manufactured by onsemi, belonging to the 74HC series of high-speed CMOS logic devices. It operates within a supply voltage range of 2V to 6V and features low static power consumption with a maximum quiescent current of 2 µA. The device provides symmetrical output drive capabilities, delivering both high and low level output currents of 5.2 mA. It is housed in a 14-SOIC surface-mount package with a width of 3.90 mm. The propagation delay is specified at a maximum of 15 ns when operating at 6V with a 50 pF load. The component supports an extended industrial operating temperature range from -40°C to +85°C.

Inverter Gates Feature Summary

• Contains four independent 2-input NOR logic gates within a single integrated circuit package.
• Utilizes high-speed CMOS technology to ensure low power dissipation and high noise immunity.
• Features robust output drive strength capable of sourcing and sinking 5.2 mA per output.
• Includes input clamp diodes to facilitate safe connection to voltages exceeding VCC via current-limiting resistors.

Inverter Gates Applications

• Digital signal processing circuits requiring logical NOR operations.
• Microcontroller peripheral interface design for address decoding or control logic.
• General-purpose combinational logic implementation in consumer electronics.
• Industrial control systems utilizing standard logic families for signal conditioning.

Inverter Gates Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure that the procurement channel sources genuine components directly from authorized distributors to guarantee authenticity. Check for RoHS compliance status and material declarations as required by project regulations. Confirm that the received parts match the MM74HC02MX designation without unauthorized modifications or alternate markings.

Inverter Gates Selection Notes

Select this component when a quad 2-input NOR function is required in space-constrained surface-mount designs. It is suitable for applications needing moderate speed performance with low standby power consumption. Consider this part for systems operating between 2V and 6V where compatibility with other 74HC series devices is necessary. Evaluate the 14-SOIC footprint constraints against available PCB real estate before finalizing the design.

Inverter Gates Part Context

This device is part of the broader 74HC logic family produced by onsemi, designed to replace older transistor-transistor logic (TTL) standards with modern CMOS alternatives. The MM74HC02MX specifically offers improved power efficiency and higher switching speeds compared to legacy NMOS or standard LS variants. It maintains pin-out compatibility with industry-standard 74HC02 definitions, facilitating straightforward upgrades in existing circuit architectures.

Inverter Gates Replacement Considerations

Cross-reference with other manufacturers' 74HC02 equivalents such as SN74HC02 or MC74HC02 for potential supply chain diversification. Verify electrical parameter alignment, particularly output current and propagation delay, before substituting. Ensure that any alternative package options maintain identical pin configurations to avoid board redesign requirements.
