Description and Introduction

4CH LOW INPUT ACTIVE HIGH .CURRENT DARLINGTON SINK DRIVER The TD62318AP is a transistor array manufactured by Toshiba. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Toshiba  
- **Type:** Transistor Array (Darlington)  
- **Number of Channels:** 7  
- **Configuration:** Darlington Pair  
- **Maximum Collector-Emitter Voltage (VCEO):** 50V  
- **Maximum Collector Current (IC):** 500mA per channel  
- **Input Voltage (VIH):** 2.4V (min)  
- **Input Voltage (VIL):** 0.8V (max)  
- **Output Saturation Voltage (VCE(sat)):** 1.6V (max) at 500mA  
- **Power Dissipation (PD):** 1.25W (per channel)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** DIP (Dual In-line Package)  
- **Pin Count:** 16  

### **Descriptions:**  
- The TD62318AP is a high-voltage, high-current Darlington transistor array.  
- It consists of seven NPN Darlington pairs with common emitters and built-in suppression diodes for inductive loads.  
- Designed for interfacing between low-level logic circuits and high-power loads (e.g., relays, lamps, motors).  

### **Features:**  
- **Built-in Clamp Diodes:** For inductive load protection.  
- **High Output Current:** 500mA per channel.  
- **Wide Operating Voltage Range:** Suitable for 5V, 12V, and 24V systems.  
- **TTL/CMOS Compatible Inputs:** Can be driven directly from logic circuits.  
- **Common Emitter Configuration:** Simplifies circuit design.  

This information is strictly based on available technical documentation for the TD62318AP by Toshiba.

Application Scenarios & Design Considerations

4CH LOW INPUT ACTIVE HIGH .CURRENT DARLINGTON SINK DRIVER

Alternative Part Number

  • ULN2003APG --: Seven-channel Darlington sink driver in DIP-16, functionally similar to the TD62318AP and widely used as a drop-in replacement for low-side relay and lamp driving.
  • ULN2803APG --: Eight-channel Darlington array in DIP-18 with higher channel count and similar sink-driver characteristics, suitable when extra channels are acceptable.
  • MC1413BDG --: Seven-channel Darlington transistor array in DIP-16 with comparable output ratings, offering a second-source option for the TD62318AP.
