To learn more about ON Semiconductor, please visit our website at Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers.

It achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The VHC4040 is a 12-stage counter which increments on the negative edge of the input clock and all outputs are reset to a low level by applying a logical high on the reset input. An input protection circuit insures that 0V to 7V can be applied to the inputs without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery backup. This circuit prevents device destruc- tion due to mismatched supply and input voltages. Ordering Information Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering number.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Recommended Operating Conditions (1) The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not recommend exceeding them or designing to absolute maximum ratings. Note: 1. Unused inputs must be held HIGH or LOW. They may not float.

I am always amazed at the cost of automotive or marine costs when a rectifier is needed while these will do the exact same thing if you are a bit technically minded to wire them up.

I am a novice technician. I really rely on reviews to help guide me, as I do not have anyone to assist me with electronics. I purchased these items and report I am happy with the purchase. I took a chance and it was one of the better choices I made.


June 7, 2020

High level customer service, and quick response.


May 31, 2020

Can't speak to the long term reliability as of yet, but they seem to be of decent quality and I don't expect any issues.


May 31, 2020

The best choice, clear and easy to make an order. Gives me full control.
