Description and Introduction

DUAL J-K FLIP FLOP WITH PRESET AND CLEAR The M74HC73B1R is a dual JK flip-flop with reset, manufactured by STMicroelectronics (STM). Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Supply Voltage Range:** 2V to 6V  
- **High Noise Immunity:** CMOS technology  
- **Low Power Consumption:**  
  - 4 µA (max) at 5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Propagation Delay:** 14 ns (typical at 5V)  
- **Output Current:** ±5.2 mA  
- **Package:** SO-14 (Small Outline)  

### **Descriptions:**  
- The M74HC73B1R consists of two independent JK flip-flops with individual J, K, clock (CP), and reset (R) inputs.  
- Each flip-flop toggles, sets, or resets based on JK inputs synchronized with the clock pulse.  
- Asynchronous reset (active LOW) clears the output independently of the clock.  

### **Features:**  
- **Dual JK Flip-Flop:** Two flip-flops in a single IC.  
- **Edge-Triggered Clocking:** Responds to the positive clock edge.  
- **Asynchronous Reset:** Immediate output clearing via reset pin.  
- **Wide Operating Voltage:** Compatible with TTL and CMOS levels.  
- **High-Speed Operation:** Suitable for high-frequency applications.  
- **ESD Protection:** HBM: 2 kV, MM: 200 V.
