NC7WZ02K8X

Overview

The NC7WZ02K8X is a dual 2-input NOR gate from onsemi's TinyLogic UHS series, manufactured using advanced CMOS technology. It operates within a wide supply voltage range of 1.65 V to 5.5 V and features low static power consumption. The device provides high output drive capability with currents up to ±32 mA at 3 V. It includes overvoltage-tolerant inputs capable of withstanding 6.5 V regardless of the supply voltage, enabling safe level shifting between 5 V and 3 V systems. Propagation delay is typically 5 ns at 3.3 V and 5 ns at 5 V under a 50 pF load.

Feature Summary

• Ultra-high-speed operation with propagation delays as low as 2.4 ns at 5 V for demanding timing applications.
• Wide operating voltage range from 1.65 V to 5.5 V ensures compatibility across diverse power environments.
• Overvoltage-tolerant inputs withstand up to 6.5 V, facilitating direct interfacing between different logic voltage levels.
• High output drive current of ±32 mA allows direct driving of loads without additional buffer circuitry.

Applications

• High-speed data bus buffering and line driving in portable electronics
• Level translation circuits between 5 V and 3.3 V logic domains
• General-purpose logic functions in space-constrained embedded systems

Procurement Notes

Verify the specific suffix K8X confirms the US-8 surface-mount package and tape-and-reel shipping configuration. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Check component lifecycle status, as availability may vary based on production schedules. Ensure input voltage tolerances match system requirements for mixed-voltage interfaces.

Selection Notes

Select this component when design constraints require minimal footprint alongside high-speed performance. The US-8 package offers a compact solution for dense PCB layouts. Consider the ±32 mA drive strength for applications requiring direct load driving. Verify that the 1.65 V minimum supply voltage aligns with the target system's power rails.
