Description and Introduction

Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs The SN74HC574 from Texas Instruments (TI) is an octal edge-triggered D-type flip-flop with 3-state outputs. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Logic Family:** HC (High-Speed CMOS)  
- **Number of Bits:** 8 (Octal)  
- **Logic Type:** D-Type Flip-Flop  
- **Output Type:** 3-State  
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Input Voltage (Min):** 2V  
- **Low-Level Input Voltage (Max):** 0.8V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Propagation Delay Time (Max):** 20 ns at 6V  
- **Output Current (High/Low):** ±7.8 mA  
- **Package Options:** SOIC, TSSOP, PDIP  

### **Descriptions:**
- The SN74HC574 is an octal flip-flop with buffered clock and output enable inputs.  
- It features edge-triggered D-type flip-flops with 3-state outputs for bus-oriented applications.  
- Data on the D inputs is transferred to the outputs on the positive edge of the clock (CP) pulse.  
- The output enable (OE) input, when high, disables the outputs, allowing them to be in a high-impedance state.  

### **Features:**
- **Wide Operating Voltage Range:** 2V to 6V  
- **High-Current 3-State Outputs:** Drive bus lines or up to 15 LSTTL loads  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation  
- **Balanced Propagation Delays:** Ensures reliable performance in high-speed applications  
- **ESD Protection:** Exceeds JESD 22 standards (2000V HBM, 1000V CDM)  
- **Latch-Up Performance:** Exceeds 250 mA per JESD 78  

This device is commonly used in data storage, bus interfacing, and register applications.
