Counter Dividers Procurement Notes
Verify the G4 suffix indicates lead-free composition and RoHS compliance per Texas Instruments standards. Confirm the NG4 designation corresponds to the PDIP-16 through-hole package variant. Ensure the component meets the specified -40°C to +85°C industrial temperature rating for your operational environment.
Counter Dividers Selection Notes
Select this component when a synchronous 4-bit binary counter with asynchronous reset is required. It is suitable for designs needing wide voltage operation between 2V and 6V. The PDIP-16 package facilitates prototyping and through-hole assembly. Verify that the 44MHz maximum frequency meets your system clock requirements.
Counter Dividers Part Context
This part belongs to the Texas Instruments SN74HC161 family of high-speed CMOS logic devices. It serves as a standard solution for digital counting applications requiring reliable synchronous operation.
