The M74HC4017 is a high speed CMOS decade counter/divider fabricated with silicon gate C2MOS technology. The M74HC4017 is a 5-stage Johnson counter with 10 decoded outputs. Each of the decoded outputs is normally low and sequentially goes high on the low to high transition of the clock input. Each output stays high for one clock period of the 10 clock period cycle. The CARRY output goes low to high after OUTPUT 10 goes low, and can be used in conjunction with the CLOCK ENABLE (CKEN)to cascade several stages. The CLOCK ENABLE input disables counting when in the high state. A CLEAR (CLR) input is also provided which when taken high sets all the decoded outputs low. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
The M74HC4017 is a high-speed CMOS decade counter/divider fabricated with silicon gate CMOS technology. It functions as a 5-stage Johnson counter with 10 decoded outputs, where each output is normally low and sequentially goes high on the low-to-high transition of the clock input. The device includes a CARRY output for cascading stages and a CLOCK ENABLE input to disable counting when high.
| Supply Voltage Range | 2V to 6V |
|---|---|
| Maximum Operating Temperature | +125 °C |
| Number of Decoded Outputs | 10 |
The device operates with a supply voltage between 2V and 6V.
It has 10 decoded outputs that are normally low and go high sequentially.
Taking the CLEAR input high sets all the decoded outputs low.
