Description and Introduction

SHIFT REGISTERS WITH J-/K SERIAL INPUTS The SN74LS195AJ is a 4-bit parallel-access shift register manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Bits:** 4-bit  
- **Function:** Parallel-in, serial-out (PISO) or serial-in, parallel-out (SIPO) shift register  
- **Operating Voltage:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** 16-pin CDIP (Ceramic Dual In-Line Package)  
- **Propagation Delay:** Typically 20ns  
- **Output Type:** TTL (Transistor-Transistor Logic) compatible  

### **Descriptions:**  
The SN74LS195AJ is a versatile shift register that can operate in both serial and parallel modes. It features asynchronous parallel load capability, allowing data to be loaded directly into the register. It also supports right-shift operations with serial data input.  

### **Features:**  
- **Parallel Load Capability:** Enables direct loading of data into the register.  
- **Serial and Parallel Operation:** Can shift data serially or load data in parallel.  
- **Asynchronous Clear:** Resets the register to all zeros.  
- **Schottky Clamped Inputs:** Improves noise immunity and reduces power consumption.  
- **High-Speed Operation:** Suitable for high-performance digital systems.  
- **TTL-Compatible Inputs and Outputs:** Ensures compatibility with other TTL logic devices.  

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

Application Scenarios & Design Considerations

SHIFT REGISTERS WITH J-/K SERIAL INPUTS

Alternative Part Number

  • DM74LS195AN --: Direct 4-bit parallel-access shift register in the same LS TTL family with identical function and pinout, from a different manufacturer and naming series.
  • SN74LS194AN --: Closely related 4-bit bidirectional universal shift register in the same LS logic family; functionally similar and often used as a substitute when bidirectional operation is acceptable.
  • CD74HCT195E --: HCT CMOS equivalent 4-bit parallel shift register with TTL-compatible inputs, offering a lower-power alternative in a different logic series.
  • DM74LS195AJ --: Direct equivalent 4-bit parallel-access shift register in the same LS TTL family with identical pinout and function.
  • 74LS195APC --: Pin-compatible 4-bit universal shift register offering the same logic function and TTL-compatible levels.
  • MC74LS195AN --: Equivalent LS TTL 4-bit shift register with matching pinout and operating characteristics for drop-in replacement.
