Description and Introduction

8-Bit Parallel-Out Serial Shift Registers The SN74ALS164AN is a 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** Shift Register  
- **Number of Bits:** 8  
- **Output Type:** Standard  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package / Case:** PDIP-14  
- **Mounting Type:** Through Hole  
- **Propagation Delay Time:** 22ns (max)  
- **High-Level Output Current:** -2.6mA  
- **Low-Level Output Current:** 24mA  
- **Clock Frequency:** 25MHz (typical)  

### **Descriptions:**  
- The SN74ALS164AN is a high-speed, low-power 8-bit shift register with serial input and parallel output.  
- It features two serial data inputs (A and B) that are ANDed together, allowing flexible data entry.  
- A master reset (MR) pin clears all flip-flops asynchronously.  
- Clock (CP) input triggers data shifting on the rising edge.  

### **Features:**  
- **8-bit serial-in, parallel-out operation**  
- **Gated serial inputs (A & B)**  
- **Asynchronous master reset**  
- **Wide operating voltage range (4.5V–5.5V)**  
- **TTL-compatible inputs and outputs**  
- **High noise immunity**  
- **Low power consumption**  

This device is commonly used in applications such as serial-to-parallel data conversion, LED displays, and digital signal processing.
