Description and Introduction

Dual Positive-Edge-Triggered D-Type Flip-Flops With Clear and Preset The SN74AHC74DBLE is a dual positive-edge-triggered D-type flip-flop from Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Technology Family:** AHC (Advanced High-Speed CMOS)  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **High-Level Input Voltage (Min):** 2 V  
- **Low-Level Input Voltage (Max):** 0.8 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Drive Capability:** ±8 mA at 5 V  
- **Propagation Delay:** 7.5 ns (typical at 5 V)  
- **Package Type:** SSOP (DB) – 14 pins  
- **Logic Type:** D-Type Flip-Flop  

### **Descriptions:**  
- The SN74AHC74DBLE features two independent D-type flip-flops with individual clear (CLR) and preset (PRE) inputs.  
- Data is transferred to the output (Q) on the positive edge of the clock (CLK) pulse.  
- Buffered inputs and outputs improve noise immunity.  

### **Features:**  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **Low Power Consumption:** Optimized for battery-operated applications  
- **High Noise Immunity:** CMOS input levels  
- **Balanced Propagation Delays:** Ensures reliable performance  
- **ESD Protection:** Exceeds 2000 V (HBM)  
- **Latch-Up Performance:** Exceeds 250 mA per JESD 17  

This device is suitable for applications requiring edge-triggered flip-flops, such as registers, counters, and control logic.
