Description and Introduction

DUAL D TYPE FLIP FLOP WITH PRESET AND CLEAR The M74HC74B1R is a dual D-type flip-flop with set and reset, manufactured by STMicroelectronics. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Supply Voltage Range:** 2V to 6V  
- **High Noise Immunity:** CMOS technology  
- **Low Power Consumption:** 4µA (max) at 5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **High-Speed Operation:** 20ns (typ) propagation delay at 5V  
- **Output Drive Capability:** 10 LSTTL loads  
- **Compliance:** Compliant with JEDEC standard No. 7A  

### **Descriptions:**  
- The M74HC74B1R consists of two independent D-type flip-flops with individual set (SD) and reset (RD) inputs.  
- Each flip-flop features a data (D) input, clock (CP) input, and complementary outputs (Q and Q̅).  
- The device operates synchronously with the clock signal, transferring data from the D input to the Q output on the rising edge of the clock pulse.  

### **Features:**  
- **Dual Flip-Flop:** Two independent D-type flip-flops in a single package.  
- **Asynchronous Set/Reset:** Direct set (SD) and reset (RD) inputs override clock and data inputs.  
- **Wide Voltage Range:** Operates from 2V to 6V, making it suitable for various applications.  
- **Balanced Propagation Delays:** Ensures reliable performance in sequential logic circuits.  
- **Schmitt Trigger Inputs:** Enhances noise immunity on clock inputs.  
- **Package Type:** Available in SO-14 package.  

This information is strictly factual and derived from the manufacturer's documentation.
