Description and Introduction

DUAL D TYPE FLIP FLOP WITH PRESET AND CLEAR The **M74HC74B1** is a dual D-type flip-flop integrated circuit (IC) manufactured by **STMicroelectronics (STM)**. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Technology:** High-Speed CMOS (HC)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +125°C  
- **High Noise Immunity:** CMOS-compatible  
- **Low Power Consumption:** Typically 4µA (static)  
- **Propagation Delay:** 14ns (typical at 5V)  
- **Output Drive Capability:** 10 LSTTL loads  
- **Package Options:** DIP-14, SO-14  

### **Descriptions:**  
- The **M74HC74B1** consists of two independent D-type flip-flops with **asynchronous set (SD) and reset (RD) inputs**, clock (CP) inputs, and complementary outputs (Q and Q̅).  
- Each flip-flop stores a single bit of data, which is transferred to the output on the rising edge of the clock signal.  
- The **asynchronous inputs (SD and RD)** override the clock and data inputs, allowing immediate setting or clearing of the flip-flop.  

### **Features:**  
- **Dual Flip-Flop:** Two independent D-type flip-flops in a single IC.  
- **Edge-Triggered Clocking:** Data is latched on the **positive edge** of the clock pulse.  
- **Asynchronous Clear and Preset:** Direct control over flip-flop states.  
- **Wide Operating Voltage:** Compatible with 2V to 6V systems.  
- **Balanced Propagation Delays:** Ensures reliable synchronous operation.  
- **High Noise Immunity:** Meets standard CMOS noise rejection levels.  

This information is based on the manufacturer's datasheet for the **M74HC74B1** by **STMicroelectronics**. For detailed electrical characteristics and timing diagrams, refer to the official datasheet.
