NLV74HC390ADR2G

Counter Dividers Overview

The NLV74HC390ADR2G is a dual decade counter integrated circuit from the onsemi 74HC series. It features two independent four-bit binary counters with asynchronous reset inputs, housed in a 16-SOIC package. The device operates within a supply voltage range of 2 V to 6 V and supports counting rates up to 50 MHz. It is designed for surface-mount installation and functions reliably across an extended industrial temperature range of -55°C to +125°C.

Counter Dividers Feature Summary

• Contains two independent four-bit synchronous decade counters
• Features asynchronous reset functionality for immediate initialization
• Supports high-speed operation with a maximum counting rate of 50 MHz
• Operates over an extended industrial temperature range

Counter Dividers Applications

• Digital frequency division circuits
• Binary-coded decimal (BCD) counting systems
• Time-base generation in digital clocks
• Address decoding in memory structures

Counter Dividers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific environmental certifications required by your region. Ensure the ordering suffix matches the exact reel quantity and tape specifications needed for your automated assembly line processes.

Counter Dividers Selection Notes

Select this component when dual independent decade counting is required within a single package. It is suitable for designs needing wide voltage flexibility between 2 V and 6 V. Consider the 16-SOIC footprint for PCB layout compatibility. Verify that the 50 MHz speed meets system timing requirements before finalizing the design.

Counter Dividers Part Context

This part belongs to the standard 74HC logic family, known for high-speed CMOS operation compatible with TTL inputs. The 'NLV' prefix typically indicates automotive-grade qualification or specific reliability enhancements compared to standard commercial variants. It serves as a fundamental building block for sequential logic applications requiring decade counting capabilities.

Counter Dividers Replacement Considerations

Direct substitutes include MC74HC390ADR2G. Cross-manufacturer equivalents such as Nexperia 74HC390D,653 or Texas Instruments CD74HC390M96 may be considered if pin-compatible and electrically equivalent.
