Description and Introduction

8-BIT SHIFT REGISTERS WITH INPUT LATCHES The SN54LS597J is a 8-bit shift register manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Series:** SN54LS  
- **Package:** Ceramic DIP (Dual In-line Package)  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Bits:** 8-bit  
- **Function:** Parallel-in, Serial-out (PISO) Shift Register  
- **Operating Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C (Military-grade)  
- **Output Type:** Tri-State  
- **Clock Frequency:** Up to 25 MHz (typical)  
- **Propagation Delay:** ~30 ns (typical)  
- **Input/Output Compatibility:** TTL  

### **Descriptions:**  
- The SN54LS597J is an 8-bit shift register with parallel input and serial output functionality.  
- It is designed for high-speed data transfer and storage applications.  
- The device features a tri-state output, allowing multiple registers to share a common bus.  
- It is part of the SN54LS series, which is the military-grade version with a wider temperature range.  

### **Features:**  
- **8-bit Parallel-in, Serial-out (PISO) Shift Register**  
- **Tri-State Outputs** for bus-oriented applications  
- **Schottky-clamped** for improved performance  
- **Wide Operating Temperature Range** (-55°C to +125°C)  
- **Low Power Consumption** (typical of LS series)  
- **TTL-Compatible Inputs and Outputs**  
- **High Noise Immunity**  

This information is strictly factual and derived from Ic-phoenix technical data files. No additional guidance or suggestions are included.

Application Scenarios & Design Considerations

8-BIT SHIFT REGISTERS WITH INPUT LATCHES

Alternative Part Number

  • CD74HC597E --: High-speed CMOS 8-bit shift register with input latch, functionally equivalent to the LS597 and pin-compatible in most DIP designs.
  • MC74HC597N --: CMOS 8-bit shift register with input storage, direct functional replacement for the 54LS597 with lower power consumption.
  • SN74LS597N --: Same LS597 function in commercial temperature range DIP package, suitable when military temperature range is not required.
  • SN74HC597N --: CMOS 8-bit parallel-load shift register with input latch, same logic function and DIP footprint, suitable when LS speed is not required.
