Description and Introduction

8-Bit Shift Register The TPIC6595 is a monolithic, high-voltage, high-current power logic 8-bit shift register manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Shift Register  
- **Output Type:** Open Drain  
- **Number of Bits:** 8  
- **Voltage Supply (VCC):** 4.5V to 5.5V  
- **Output Voltage (Max):** 50V  
- **Output Current (Max):** 150mA per output (sink)  
- **Power Dissipation:** 2W  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** PDIP (20-pin), SOIC (20-pin)  

### **Descriptions and Features:**  
- Designed for high-voltage, high-current applications.  
- Contains an 8-bit serial-in, parallel-out shift register feeding an 8-bit D-type storage register.  
- Open-drain DMOS transistor outputs with 50V rating and 150mA sink current capability.  
- Suitable for driving relays, solenoids, and other high-power loads.  
- Includes output clamp diodes for inductive transient protection.  
- Compatible with standard TTL and CMOS logic levels.  
- Features a serial output for cascading multiple devices.  

For detailed electrical characteristics and timing diagrams, refer to the official TI datasheet.

Application Scenarios & Design Considerations

8-Bit Shift Register

Alternative Part Number

  • 74HC595 --: 8-bit serial-in/parallel-out shift register with output latches, functionally similar to the TPIC6595 shift register stage; widely available and low cost, though it lacks the high-current open-drain outputs.
  • MIC5891 --: 8-bit serial-input latched driver with high-voltage, high-current open-drain outputs, closely matching the TPIC6595 power shift register function for driving relays and LEDs.
  • UDN2981A --: 8-channel source driver with high-current outputs, suitable as a functional substitute for driving loads in place of the TPIC6595, though it uses a different interface style.
