Counter Dividers Procurement Notes

Verify the specific suffix 'ANSR' confirms the SOP-16 surface-mount package and reel packaging format. Ensure the component meets the required operating temperature range of -40°C to +85°C for your application environment. Confirm RoHS compliance status matches current regulatory requirements before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with low power consumption is required. The HC series offers compatibility with standard CMOS logic levels. Consider the SOP-16 package for automated surface-mount assembly processes. Verify that the 2 V to 6 V supply voltage range aligns with the system power design constraints.

Counter Dividers Part Context

This part belongs to the SN74HC161 family of synchronous binary counters. It shares functional similarities with other 74HC series logic devices but is optimized for high-speed digital applications. The AS suffix variant indicates specific performance characteristics distinct from standard LS or F series counterparts.
