M74HC4040B1R

Counter Dividers Overview

The M74HC4040B1R is a 12-stage asynchronous binary ripple counter from the STMicroelectronics 74HC series. It operates within a supply voltage range of 2 V to 6 V and supports through-hole installation in a 16-DIP package. The device features negative edge-triggered flip-flops, an asynchronous reset function, and unidirectional up-counting capability. It functions reliably across an extended temperature range from -55 °C to +125 °C.

Counter Dividers Feature Summary

• Asynchronous 12-bit binary counting with negative edge triggering
• Integrated asynchronous reset functionality for immediate state clearing
• Wide operating voltage compatibility supporting low-power applications

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation for timing systems
• Event sequence counting logic

Counter Dividers Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package integrity and pin alignment prior to assembly. Ensure storage conditions comply with moisture sensitivity level requirements to prevent soldering defects during reflow processes.

Counter Dividers Selection Notes

Select this component when a high-density 12-bit counter is required in a through-hole configuration. Consider the HC logic family for standard CMOS performance. Evaluate alternative packages if surface-mount space constraints exist or if different trigger polarity is needed for specific system synchronization.
