Description and Introduction

Bidirectional shift registers 24-PDIP 0 to 70 The SN74198N is a 8-bit parallel-in/parallel-out shift register manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Shift Register  
- **Number of Bits:** 8  
- **Function:** Parallel-In/Parallel-Out  
- **Supply Voltage (VCC):** 4.75V to 5.25V (Standard 5V operation)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** PDIP (Plastic Dual In-Line Package)  
- **Mounting Type:** Through-Hole  
- **Output Type:** Tri-State  

### **Descriptions:**  
- The SN74198N is a versatile 8-bit shift register capable of parallel or serial data loading.  
- It supports bidirectional shifting (left or right) based on control inputs.  
- Features synchronous parallel loading and asynchronous master reset.  
- Tri-state outputs allow bus-oriented applications.  

### **Features:**  
- **Parallel and Serial Data Entry**  
- **Bidirectional Shift Capability** (Left or Right)  
- **Synchronous Parallel Load**  
- **Asynchronous Master Reset**  
- **Tri-State Outputs** for bus compatibility  
- **TTL-Compatible Inputs and Outputs**  
- **Wide Operating Voltage Range** (4.75V to 5.25V)  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and timing diagrams, refer to the official TI documentation.

Application Scenarios & Design Considerations

Bidirectional shift registers 24-PDIP 0 to 70

Alternative Part Number

  • CD40194BE --: CMOS 4-bit bidirectional universal shift register with parallel I/O, functionally similar to the 74198 and pin-compatible in many designs with lower power consumption.
  • MC74HC194N --: High-speed CMOS 4-bit bidirectional universal shift register, direct functional replacement for the 74198 with compatible parallel load and shift modes.
  • 74F194PC --: Fast TTL 4-bit bidirectional universal shift register in DIP package, same logic function and pinout as the SN74198N with improved speed.
  • MC14504BCP --: Hex level shifter often used alongside shift-register logic; not a direct equivalent, but a commonly stocked DIP alternative when the SN74198N is unavailable.
  • 74HC194N --: 4-bit bidirectional universal shift register in DIP, pin-compatible with the 74198 family and a widely available CMOS alternative.
