The HCF4040B is a 12-bit binary counter/divider from Honeywell with a working voltage range of 5V, 10V and 15V, a working frequency of 80ns, fully static operation, standardized symmetrical output characteristics, input leakage current of 100nA (maximum), 100% tested for static current.
The HCF4040B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology, available in DIP and SOP packages. It functions as a ripple carry binary counter where all counter stages are master-slave flip-flops, advancing one count on the negative transition of each input pulse.
| Number of Stages | 12 Stage |
|---|---|
| Operating Temperature Range | -55 to +125 °C |
| Package Types | DIP and SOP |
The state of the counter advances one count on the negative transition of each input pulse.
A high level on the RESET line resets the counter to its all zeros stage.
