MC74AC02N

Inverter Gates Overview

The MC74AC02N is a quad 2-input NOR gate from the onsemi AC logic series, housed in a 14-pin PDIP package. It operates within a supply voltage range of 2 V to 6 V. The device features outputs capable of sourcing and sinking 24 mA. Propagation delay is specified at 8 ns when operating at 5 V with a 50 pF load. The component supports low-level input logic voltages between 0.9 V and 1.65 V, and high-level input logic voltages between 2.1 V and 3.85 V. Quiescent current is maximized at 4 µA. Operating temperature ranges from -55 °C to 125 °C.

Inverter Gates Feature Summary

• Provides four independent 2-input NOR logic functions within a single integrated circuit.
• Features buffered outputs with high drive capability for direct interface with loads.
• Supports TTL-compatible inputs for compatibility with standard digital logic families.

Inverter Gates Applications

• General-purpose digital logic processing
• Microprocessor system interfaces
• Memory address decoding circuits

Inverter Gates Procurement Notes

Verify the specific suffix 'N' corresponds to the PDIP-14 through-hole package variant rather than surface-mount options like DR or DG. Confirm RoHS compliance status as older PDIP variants may differ from modern reel-packaged equivalents. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout mismatches in legacy designs.

Inverter Gates Selection Notes

Select this component when through-hole mounting is required for the AC logic family. It offers higher output current compared to standard LS series devices while maintaining similar pinouts. Consider the wider operating temperature range if the application involves harsh environmental conditions. Verify that the 2V minimum supply voltage aligns with the system power rails.

Inverter Gates Part Context

This part belongs to the MC74AC02 family, which includes variants such as MC74AC02DG and MC74AC02DR2G. These alternatives share identical logical functionality but differ in packaging technology. The AC series represents a high-speed CMOS technology developed by onsemi, succeeding earlier HC and HCT series in performance metrics for general logic applications.

Inverter Gates Replacement Considerations

CD74AC00E and SN74AC00N are listed as similar functional replacements from Texas Instruments, though they represent NAND gates. Direct substitutes for the NOR function should be verified against specific datasheet electrical characteristics and pin configurations.
