Circuit Diagram for XD14553 Counter Shift Register

The following circuit diagram demonstrates the use of the XD14553 to drive a three-digit 7-segment display for counting applications.

Components Required:

• XD14553 Counter Shift Register (1x)

• 7-Segment Display (Common Cathode) (3x)

• BCD to 7-Segment Decoder (CD4511) (3x)

• Resistors (330O) (7x)

2. Clock Input: Connect a push-button switch to Clock Input (Pin 1) to provide counting pulses.

3. Digit Outputs: Connect the three BCD outputs to separate CD4511 decoders, which drive the 7-segment displays.

4. Display Multiplexing: Use the Digit Select output to control which 7-segment display is active at a given time.

5. Latch Enable: Tie the Latch Enable (Pin 3) to High to store the current count.

Use Case Scenario

Digital Event Counter for Manufacturing Systems

Objective:

A factory wants to keep a real-time count of items passing on a conveyor belt.

Solution:

The XD14553 is implemented in an event counter circuit that tracks each item as it passes a proximity sensor. The sensor outputs a pulse every time an object is detected. The XD14553 counts these pulses and displays the total count on a 3-digit 7-segment display.

Implementation:

1. Sensor Integration: A proximity sensor (IR or optical) generates an electrical pulse when an item passes.

2. Pulse Processing: The pulse is fed into the Clock Input (Pin 1) of the XD14553.

3. Counting & Display: The IC counts the pulses and updates the 7-segment display via a BCD to 7-segment decoder.

4. Reset Mechanism: A manual reset button resets the count when needed.

Outcome:

The factory gets an accurate count of produced items, helping in inventory tracking and quality control.

Alternative Components

If the XD14553 is unavailable, consider these alternative ICs:

• CD4026 – A decade counter with direct 7-segment display driving.

• 74LS192 – A presettable BCD up/down counter.

• 74LS90 – A decade counter that can be used for counting applications.
