MM74C90N

Counter Dividers Overview

The MM74C90N is a 4-bit decade counter integrated circuit manufactured by onsemi, utilizing complementary MOS (CMOS) technology. It operates within a supply voltage range of 3V to 15V and features a 14-lead Plastic Dual-In-Line Package (PDIP). The device supports reset to zero or preset to nine via dedicated inputs and includes a separate flip-flop for divide-by-2, 5, or 10 frequency counting functions. Propagation delay ranges from 200ns to 1200ns depending on the output stage and supply voltage.

Counter Dividers Feature Summary

• Capable of resetting to zero or presetting to nine through specific logic level inputs
• Includes a separate flip-flop enabling divide-by-2, 5, or 10 frequency division operations
• Provides high noise immunity with a guaranteed noise margin of 1V

Counter Dividers Applications

• Frequency counters
• Digital timing circuits
• BCD counting sequences

Counter Dividers Procurement Notes

Verify component authenticity as this part may be sourced from third-party distributors. Confirm package integrity and pin alignment against the 14-PDIP specification. Check datasheet revisions for any electrical characteristic updates. Ensure compliance with RoHS requirements if applicable to your system constraints.

Counter Dividers Selection Notes

Select this component when a decade counting sequence is required rather than binary. Consider the wide operating voltage range suitable for various logic families. Evaluate propagation delays against system clock speeds. Verify that the PDIP package fits the available PCB footprint.

Counter Dividers Part Context

This component belongs to the MM74C series of CMOS logic devices. It serves as a functional alternative to TTL counters but offers lower power consumption. The device is designed for general-purpose digital counting applications requiring decade sequencing capabilities.

Counter Dividers Replacement Considerations

MM74C93N is a compatible binary counter variant within the same family.
