Frequently Asked Questions
What is the maximum operating temperature range for this counter?
The operating temperature range (T) is from -40°C to +85°C.
Does the VHC4040 offer protection against input voltage swings?
Yes, it includes an input protection circuit providing power-down protection on all inputs, allowing voltages between 0V and 7V.
What type of package options are available for ordering?
Available packages include SOIC (M16A), TSSOP (MTC16), and PDIP (N16E). Surface mount versions also exist on Tape and Reel.
How is the counter reset to a low level?
Outputs are reset to a low level by applying a logical high signal to the master reset (MR) input pin.
