Description and Introduction

Octal D-type Latch The TPIC6B273DW is a monolithic, high-voltage, high-current power logic 8-bit D-type latch manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** D-Type Latch  
- **Number of Bits:** 8  
- **Output Type:** Open Drain  
- **Voltage Supply (VCC):** 4.5V to 5.5V  
- **Output Voltage (Max):** 50V  
- **Output Current (Max):** 150mA per channel  
- **Propagation Delay (Max):** 45ns  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-20 (DW)  

### **Descriptions:**  
- The TPIC6B273DW is designed for applications requiring high-voltage and high-current outputs, such as driving relays, solenoids, and lamps.  
- It features 8 D-type latches with open-drain DMOS transistor outputs, capable of sinking up to 150mA per channel.  
- The device includes a clear input to reset all latches simultaneously.  

### **Features:**  
- **High-Voltage Outputs:** Up to 50V  
- **High-Current Sink Capability:** 150mA per channel  
- **Low Power Consumption**  
- **8-Bit Parallel Output Storage**  
- **ESD Protection:** Up to 2kV (HBM)  
- **Latch-Up Performance Exceeds 500mA**  
- **Compatible with Standard TTL Logic Levels**  

This information is sourced from the Texas Instruments datasheet for the TPIC6B273DW.

Application Scenarios & Design Considerations

Octal D-type Latch

Alternative Part Number

  • MC74HC273ADWG --: Octal D-type flip-flop with clear in a 20-pin SOIC wide-body package, functionally similar to the TPIC6B273DW; note it uses standard CMOS outputs rather than the DMOS power outputs of the original, so verify drive requirements.
  • SN74HC273DWR --: Same manufacturer octal D flip-flop with clear in a wide SOIC package, pin-compatible logic function; however it lacks the high-current DMOS outputs, so it suits only low-current load applications.
  • ULN2803ADWR --: Eight-channel Darlington sink driver in a wide SOIC package that can replace the power-driving role of the TPIC6B273DW for inductive or high-current loads, though it is a driver array rather than a flip-flop and requires external latching logic.
