Key Features
- Johnson Decade Counter: Counts in a sequence of ten states, providing ten decoded outputs (Q0 to Q9).
- Dual Clock Inputs: The counter can be advanced by either a LOW-to-HIGH transition at CP0 while CP1 is LOW or a HIGH-to-LOW transition at CP1 while CP0 is HIGH.
- Asynchronous Master Reset: Resets the counter to zero (Q0 = Q5-9 = HIGH; Q1 to Q9 = LOW) independent of the clock inputs.
- Automatic Code Correction: Returns to a proper counting mode within 11 clock pulses after any illegal code.
- Input Clamp Diodes: Enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
- Low Power Dissipation: CMOS technology ensures low power consumption.
- High Noise Immunity: Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.
Applications
- Counting and Sequencing: Ideal for applications requiring a decade counter, such as in digital circuits, timing circuits, and sequential logic circuits.
- Automotive Systems: Suitable for use in automotive systems due to its wide operating temperature range and robust ESD protection.
- Industrial Control Systems: Used in industrial control systems for counting and sequencing tasks.
- Consumer Electronics: Found in various consumer electronics requiring counting functions, such as timers and sequencers.
