Description and Introduction

Dual 2-Wide 2-Input AND-OR-invert Gates (One Gate Expandable) The SN5450J is a dual J-K flip-flop with preset and clear, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** J-K Flip-flop  
- **Number of Circuits:** 2  
- **Output Type:** Standard  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Output Current (IOH):** -0.4mA  
- **Low-Level Output Current (IOL):** 16mA  
- **Propagation Delay Time (tpd):** 40ns (max)  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package Type:** Ceramic DIP (Dual In-line Package)  

### **Descriptions and Features:**  
- Contains two independent J-K flip-flops with individual J, K, clock, preset, and clear inputs.  
- Direct clear and preset override the clocked inputs.  
- High noise immunity and low power consumption.  
- Compatible with most TTL families.  
- Suitable for counter, register, and control applications.  

This device is part of TI's legacy 5400 series, designed for military and industrial applications with extended temperature ranges.

Application Scenarios & Design Considerations

Dual 2-Wide 2-Input AND-OR-invert Gates (One Gate Expandable)

Alternative Part Number

  • DM74LS50N --: Same 2-wide 4-input AND-OR-INVERT gate function in a DIP package, pin-compatible with the SN5450J logic function.
  • MC74HC50N --: CMOS equivalent of the 50-series AND-OR-INVERT gate, offering lower power consumption and similar logic behavior.
  • CD74HCT50E --: High-speed CMOS version of the 50-series gate with TTL-compatible inputs, suitable as a functional replacement.
  • MC1450BCP --: Pin-compatible dual peripheral driver with similar electrical characteristics, widely available and often used as a direct substitute in legacy designs.
  • DS75450N --: Equivalent dual peripheral driver in a DIP package with comparable drive current and voltage ratings, suitable for drop-in replacement.
  • UHP450 --: Similar dual driver function with matched pinout and ratings, commonly cross-referenced for SN5450 applications.
