Description and Introduction

4-BIT PARALLEL-ACCESS SHIFT REGISTERS The SN54S195J is a 4-bit universal shift register manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Universal Shift Register  
- **Number of Bits:** 4  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package Type:** Ceramic DIP (Dual In-line Package)  
- **Logic Family:** S-Series (Schottky TTL)  
- **Propagation Delay:** Typically 20ns  
- **Input/Output Compatibility:** TTL  

### **Descriptions and Features:**  
- **Universal Operation:** Can perform parallel load, shift left, shift right, and hold operations.  
- **Synchronous Operation:** Controlled by a clock input.  
- **Parallel Inputs/Outputs:** Allows data to be loaded in parallel or shifted serially.  
- **Direct Overriding Clear (CLR):** Asynchronous reset function.  
- **Schottky-Clamped:** Improves switching speed and reduces power consumption compared to standard TTL.  
- **Military-Grade (SN54 Series):** Designed for high-reliability applications.  

This device is commonly used in data storage, serial-to-parallel conversion, and arithmetic operations in digital systems.

Application Scenarios & Design Considerations

4-BIT PARALLEL-ACCESS SHIFT REGISTERS

Alternative Part Number

  • CD74ACT195E --: 4-bit parallel-load shift register in the 74ACT family with similar function and pinout, available in a DIP package comparable to the original J package.
  • MC74ACT195N --: Direct functional equivalent 4-bit shift register from the 74ACT logic family, offering similar speed and drive characteristics as the SN54S195.
  • 74HC195N --: CMOS 4-bit parallel-access shift register with equivalent logic function, suitable as a lower-power substitute where TTL-level compatibility is not critical.
  • CD74HC195E --: 4-bit parallel-access shift register in the same functional family, CMOS version with similar logic function and DIP package, widely available and pin-compatible in function.
  • MC74HC195N --: Direct functional equivalent 4-bit shift register from a different manufacturer and series, offering comparable logic operation and DIP package compatibility.
  • SN74LS195AN --: Low-power Schottky 4-bit parallel-access shift register with similar function and pinout, suitable as a drop-in functional replacement in many designs.
