Counter Dividers Procurement Notes

Verify the specific suffix RM13TR against official STMicroelectronics documentation to confirm package type and reel specifications. Ensure compatibility with existing PCB footprints for the 16-SOIC form factor. Cross-reference the datasheet revision date to validate electrical characteristics against current design requirements before finalizing procurement decisions.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with asynchronous reset is required. It is appropriate for designs needing high-frequency performance up to 62 MHz. Consider the 2V-6V voltage range for flexibility in power supply design. Verify that the SOIC-16 package fits the mechanical constraints of the target assembly.

Counter Dividers Part Context

This part belongs to the M74HC161 series of synchronous presettable 4-bit binary counters. It is designed for general-purpose digital logic applications where precise counting and synchronization are necessary. The HC logic family ensures compatibility with standard TTL levels while offering CMOS low power consumption characteristics.

Counter Dividers Replacement Considerations

Check for direct pin-compatible alternatives within the same HC logic family. Verify that any substitute maintains the 62 MHz maximum frequency and asynchronous reset feature. Ensure the replacement part supports the same 16-SOIC package and voltage range.
