The TC4017BP is a 5-Stage Johnson Counter manufactured by Toshiba Semiconductor and Storage, utilizing CMOS technology for low power consumption and high noise immunity. This device is designed to function as a Johnson decade counter, providing ten decoded outputs that activate sequentially. It's commonly used for creating sequential control signals, generating timing sequences, and driving discrete displays. The TC4017BP includes a clock input, a reset input to initialize the counter, and a carry-out signal for cascading multiple devices.

Applications:

• Sequential lighting displays and effects
• Stepping motor control circuits
• Timing and sequencing applications
• Event counters and controllers
• Digital display driving

Features:

• 5-Stage Johnson Counter: Implements a Johnson counter for generating sequential outputs.
• Ten Decoded Outputs: Provides ten distinct, sequentially activated outputs.
• Clock Input: Advances the counter state with each clock pulse.
• Reset Input: Sets the counter to its initial state.
• Carry-Out Signal: Facilitates cascading multiple devices for extended counting.
• CMOS Logic: Offers low power consumption and excellent noise immunity.

Benefits:

• Simplified Sequencing: Simplifies the generation of complex sequential control signals.
• Reduced Component Count: Integrates the functionality of a decade counter into a single IC.
• Easy Expansion: The carry-out signal enables easy cascading for larger counting ranges.
• Low Power Consumption: Suitable for battery-powered and energy-sensitive applications.
• Reliable Operation: CMOS technology ensures robust operation even in noisy environments.

Additional Details:

The TC4017BP comes in a DIP (Dual In-line Package). The counter advances its sequence on each positive-going clock edge. Only one of the ten decoded outputs is high at any given time, progressing sequentially with each clock pulse. Activating the reset input returns the counter to its initial state, where the '0' output is high and all other outputs are low. The carry-out signal transitions high after a full counting cycle, enabling the cascading of multiple TC4017BP devices. The device datasheet provides comprehensive details regarding timing characteristics, truth tables, and application examples.
