Description and Introduction

CCD LINEAR IMAGE SENSOR The TCD2554D is a linear image sensor manufactured by Toshiba. Below are the specifications, descriptions, and features based on the available knowledge:  

### **Specifications:**  
- **Type:** CCD Linear Image Sensor  
- **Number of Pixels:** 5340 (effective pixels)  
- **Pixel Size:** 8.5 µm (H) × 8.5 µm (V)  
- **Total Length:** Approximately 45.4 mm  
- **Outputs:** 2-channel output  
- **Clock Frequency:** Up to 20 MHz  
- **Supply Voltage:** Typically 12 V (analog), 5 V (digital)  
- **Sensitivity:** High sensitivity in visible light range  
- **Package:** Ceramic DIP (Dual In-line Package)  

### **Descriptions:**  
- The TCD2554D is designed for high-resolution scanning applications such as document scanners, fax machines, and optical measurement systems.  
- It features a built-in sample-and-hold circuit for improved signal processing.  
- The sensor operates in a time-delay integration (TDI) mode for enhanced sensitivity.  

### **Features:**  
- **High Resolution:** 5340 effective pixels for detailed image capture.  
- **Dual Output:** Two output channels for faster data readout.  
- **Low Noise:** Optimized for high signal-to-noise ratio (SNR).  
- **Wide Dynamic Range:** Suitable for varying light conditions.  
- **Compact Design:** Ceramic DIP package ensures durability and heat dissipation.

Application Scenarios & Design Considerations

CCD LINEAR IMAGE SENSOR

Alternative Part Number

  • MN3455D --: Similar CCD linear image sensor with comparable pixel count and supply requirements, often used as a drop-in substitute in scanner and imaging designs.
  • ILX554B --: CCD linear sensor with similar resolution and pin-compatible analog output, widely available and commonly cross-referenced for Toshiba TCD-series sensors.
  • TCD1304DG --: Same Toshiba CCD linear sensor family with comparable architecture and drive signals, suitable when minor pixel-count differences are acceptable.
  • TC74HC245AF --: Toshiba octal bus transceiver in the same logic family, commonly used as a functional substitute for the TCD2554D buffer/driver in many designs.
  • SN74HC245N --: Widely available octal bus transceiver with equivalent logic function and pinout, offering a second-source option with broad supply availability.
  • MC74HC245AN --: Another second-source octal bus transceiver matching the TCD2554D function, providing a cost-effective alternative with good availability.
