Description and Introduction

Parallel-Load 8-Bit Serial Shift Registers The SN74ALS165 is a parallel-load 8-bit shift register manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Shift Register  
- **Number of Bits:** 8  
- **Input Type:** Parallel/Serial  
- **Output Type:** Serial  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Propagation Delay (tpd):** Typically 13ns (max 22ns)  
- **Power Dissipation:** Low power consumption (ALS series)  
- **Package Options:** PDIP, SOIC  

### **Descriptions:**  
- The SN74ALS165 is a high-speed, low-power 8-bit shift register with parallel or serial input.  
- It features a serial output (QH) and complementary serial output (QH̅).  
- Parallel data is loaded asynchronously when the parallel-load (PL̅) input is low.  
- Shifting occurs synchronously on the low-to-high transition of the clock (CP) input.  

### **Features:**  
- **Parallel-to-Serial Conversion**  
- **Wide Operating Voltage Range (4.5V to 5.5V)**  
- **High-Speed Operation (ALS Series)**  
- **Asynchronous Parallel Load**  
- **Synchronous Serial Shift**  
- **Complementary Outputs (QH and QH̅)**  
- **Low Power Consumption**  

This device is commonly used in data storage, serial data transfer, and digital signal processing applications.
