CD4017 - Decade Counter/Divider

CD4017 - Decade Counter/Divider

The CD4017 is a CMOS Decade Counter IC with 10 decoded outputs and a built-in divide-by-10 counter. It is widely used in digital circuits for sequencing and timing applications. Each output of the IC goes high one at a time, in sequence, with every clock pulse received at the input.

Key Features & Benefits:

• 10 Output Channels: Provides one active high output per clock cycle, perfect for LED chasers, timers, and digital sequencing.

• Divide-by-10 Counter: Acts as a frequency divider, generating one output pulse for every 10 input pulses.

• Wide Voltage Range: Operates from 3V to 15V, suitable for both TTL and CMOS logic levels.

• Low Power Consumption: CMOS technology ensures minimal power draw.

• Built-in Reset and Clock Enable: Allows flexible control in circuit operations.

• Noise Immunity: High noise immunity ensures stable operation in noisy environments.
