MC74HC02ANG

Inverter Gates Overview

The MC74HC02ANG is a high-performance silicon gate CMOS quad 2-input NOR gate manufactured by onsemi. It operates within a supply voltage range of 2 V to 6 V and features buffered outputs for high noise immunity. The device supports through-hole mounting in a 14-PDIP package. Key electrical specifications include a low-level output current of 5.2 mA, a propagation delay of 13 ns at 6 V with 50 pF load, and a maximum static power consumption of 1 µA. It functions reliably across an extended temperature range from -55 °C to +125 °C.

Inverter Gates Feature Summary

• High-speed operation comparable to LS-TTL gates while maintaining standard CMOS low-power characteristics.
• Buffered outputs provide high noise immunity and stable signal integrity.
• Input compatibility with standard CMOS outputs; LSTTL compatibility achievable via pull-up resistors.

Inverter Gates Applications

• General-purpose digital logic circuit design
• Signal processing systems requiring NOR logic functions
• Industrial control applications operating in wide temperature environments

Inverter Gates Procurement Notes

Verify the specific suffix 'ANG' against the manufacturer's official datasheet to confirm pinout and electrical parameters match your design requirements. Confirm RoHS compliance status directly with onsemi documentation. Check for end-of-life notices or product change notifications (PCN) as availability may be limited. Ensure the 14-PDIP package dimensions align with your PCB footprint constraints before finalizing procurement.

Inverter Gates Selection Notes

Select this component when a quad 2-input NOR function is required in a through-hole application. It serves as a direct pin-compatible replacement for older LS02 designs, offering improved speed and lower power consumption. Consider the 2 V to 6 V operating range to ensure compatibility with your system's power supply rails. Verify that the 5.2 mA drive capability meets the fan-out requirements of your connected loads.

Inverter Gates Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by onsemi. The 74HC family is designed to bridge the performance gap between standard CMOS and low-power Schottky TTL technologies. The MC74HC02A variant specifically provides four independent NOR gates, making it a fundamental building block for complex digital logic architectures requiring multiple input combinations.

Inverter Gates Replacement Considerations

Publicly confirmed direct substitutes include CD74HC02E from Texas Instruments and SN74HC02N from Rochester Electronics. These alternatives offer identical logical functionality and pin configurations. Verify that any substitute component matches the specific voltage and temperature ratings required for your application environment.
