Description and Introduction

Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs The SN74ABT574AN is a high-performance, octal edge-triggered D-type flip-flop manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Logic Type:** D-Type Flip-Flop  
- **Number of Bits:** 8 (Octal)  
- **Trigger Type:** Positive Edge  
- **Output Type:** 3-State  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Input Voltage (VIH):** 2V (min)  
- **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **High-Level Output Current (IOH):** -32mA  
- **Low-Level Output Current (IOL):** 64mA  
- **Propagation Delay (tpd):** 4.5ns (max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** PDIP (Plastic Dual In-Line Package)  
- **Package / Case:** 20-DIP (0.300", 7.62mm)  
- **Mounting Type:** Through Hole  

### **Descriptions:**
- The SN74ABT574AN is designed for bus-oriented applications where high-speed, low-power operation is required.  
- It features 3-state outputs that allow direct connection to a bus-organized system.  
- The flip-flops are edge-triggered, meaning data is transferred on the low-to-high transition of the clock (CLK) input.  
- The output enable (OE) input controls the 3-state outputs, enabling or disabling them as needed.  

### **Features:**
- **High-Speed Operation:** Optimized for 5V operation with fast propagation delays.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **Balanced Output Drivers:** Reduce ground bounce and switching noise.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.  
- **Flow-Through Pinout:** Simplifies PCB layout.  
- **Latch-Up Performance:** Exceeds 500mA per JESD 78.  

This device is commonly used in data storage, buffering, and bus interface applications.

Application Scenarios & Design Considerations

Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs

Alternative Part Number

  • 74ABT574APC --: Same 74ABT574 octal D-type flip-flop function with 3-state outputs, pin-compatible DIP-20 package, different manufacturer and naming prefix.
  • 74ABT574ADB --: Equivalent ABT-series octal D flip-flop with 3-state outputs, same logic family and function, different series naming from the source.
  • 74ABT574AMTC --: Functionally equivalent octal D-type flip-flop with 3-state outputs in the ABT family, suitable drop-in logic replacement.
  • 74ABT574AN --: Direct functional equivalent octal edge-triggered D-type flip-flop with 3-state outputs in DIP-20, matching logic family and pinout.
  • MC74ABT574AN --: ABT-series octal D flip-flop with 3-state outputs in DIP-20, offering comparable speed and drive characteristics as a drop-in replacement.
