MC14526BDWR2G

Counter Dividers Overview

The MC14526BDWR2G is a single 4-bit asynchronous binary down counter manufactured by onsemi. It operates within a supply voltage range of 3 V to 18 V and supports clock frequencies up to 6.6 MHz. The device utilizes positive and negative trigger flip-flops for counting operations. It is housed in a 16-pin SOIC wide package with a width of 7.50 mm. The component functions reliably across an extended temperature range from -55°C to +125°C.

Counter Dividers Feature Summary

• Asynchronous reset capability for immediate state initialization
• Single-directional downward binary counting logic
• Wide operating voltage tolerance for flexible power integration

Counter Dividers Applications

• Digital frequency division circuits
• Binary countdown timers
• Event sequence counters

Counter Dividers Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance status, as historical data suggests variations in environmental declarations between the non-G and G variants. Confirm the package dimensions match the 16-SOIC specification with a 7.50 mm width. Ensure the supplier provides official datasheets confirming the 6.6 MHz maximum clock rate and the -55°C to +125°C operating temperature range before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a simple, low-cost asynchronous binary down counter is required for digital logic applications. It is suitable for designs needing a wide supply voltage range and robust industrial temperature performance. Consider the 16-pin SOIC package for surface-mount assembly constraints. Verify that the asynchronous reset function meets the system's timing requirements compared to synchronous alternatives.

Counter Dividers Part Context
