Description and Introduction

Octal D-Type Edge-Triggered Flip-Flops With 3-State Outputs The SN74ALS564BN is a part of the 74ALS series of integrated circuits, manufactured by Texas Instruments.  

### **Manufacturer Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Series:** 74ALS  
- **Logic Type:** Octal D-Type Flip-Flop with 3-State Outputs  
- **Package / Case:** PDIP-20 (Plastic Dual In-Line Package, 20 pins)  
- **Mounting Type:** Through Hole  
- **Operating Temperature:** 0°C to 70°C  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Output Type:** 3-State  
- **Number of Bits per Element:** 8  
- **Propagation Delay Time (Max):** 13 ns at 5V  
- **High-Level Output Current:** -2.6 mA  
- **Low-Level Output Current:** 24 mA  

### **Descriptions and Features:**  
- **Function:** The SN74ALS564BN is an octal D-type flip-flop with 3-state outputs, designed for bus-oriented applications.  
- **Edge-Triggered:** Data is transferred on the rising edge of the clock (CLK) input.  
- **3-State Outputs:** Allows multiple devices to share a common bus without interference.  
- **Buffered Control Inputs:** Includes clock (CLK) and output enable (OE) inputs for improved noise immunity.  
- **Applications:** Used in data storage, buffering, and bus interfacing in digital systems.  
- **Compatibility:** TTL-compatible inputs and outputs.  

This device is commonly used in microprocessor and digital logic applications where data latching and bus driving are required.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • 74ALS564BN --: Same 74ALS octal D-type flip-flop with 3-state outputs in DIP-20, pin-compatible and functionally equivalent.
  • DM74ALS564BN --: Direct equivalent ALS-series octal flip-flop with inverted outputs, same package and logic function.
  • SN74ALS564BDW --: Same TI ALS564 function in SOIC-20 package, suitable when a surface-mount form factor is acceptable.
