• Digital counting systems

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'TR2' corresponds to the TSSOP-16 package configuration as documented in the official datasheet. Confirm that the component meets RoHS compliance requirements if lead-free materials are necessary for the assembly process. Ensure the operating temperature range aligns with system specifications.

Counter Dividers Selection Notes

Select this component when a 12-bit binary counter is required with direct compatibility to standard CMOS outputs. Consider the asynchronous reset functionality and negative-edge clock triggering for timing-sensitive designs. Evaluate the propagation delay characteristics against the maximum clock frequency requirements of the target application.

Counter Dividers Part Context

This part belongs to the MC74HC4040A series of high-performance silicon-gate CMOS logic devices. It is functionally identical in pinout to the standard CMOS MC14040 but offers improved speed and drive capabilities. The series is designed for general-purpose digital counting and frequency division tasks.

Counter Dividers FAQ

How does the reset function operate?

The reset is asynchronous and active-high. Applying a high level to the Reset pin forces all Q outputs low immediately.

What triggers the state change in the counter?

State changes occur on the negative-going edge of the Clock input.
