Description and Introduction

Parallel-Load 8-Bit Shift Registers The SN74LV165ADBR is a 8-bit parallel-load shift register manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** 8-Bit Parallel-Load Shift Register  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **High-Level Input Voltage (Min):** 2 V  
- **Low-Level Input Voltage (Max):** 0.8 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SSOP-16  
- **Output Type:** Push-Pull  
- **Clock Frequency (Max):** 100 MHz (at 5 V)  
- **Number of Bits per Element:** 8  
- **Propagation Delay (Max):** 11.5 ns (at 5 V)  

### **Descriptions and Features:**  
- **Parallel-to-Serial Data Conversion:** Loads data in parallel and shifts it out serially.  
- **Wide Operating Voltage:** Supports 2 V to 5.5 V, making it compatible with various logic levels.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **Synchronous Serial Data Output:** Controlled by a clock (CLK) and shift/load (SH/LD) input.  
- **Direct Overriding Clear (CLR) Input:** Asynchronously resets all flip-flops.  
- **Applications:** Data storage, serial-to-parallel conversion, and digital signal processing.  

This device is commonly used in digital systems for serial data expansion and interfacing.

Application Scenarios & Design Considerations

Parallel-Load 8-Bit Shift Registers

Alternative Part Number

  • MC74VHC165DR2G --: Direct functional equivalent 8-bit parallel-in/serial-out shift register in the same VHC logic family, available in SOIC package with similar supply voltage range and pinout.
  • 74VHC165MTCX --: Same 8-bit parallel-load shift register function with VHC speed grade, TSSOP package, and compatible electrical characteristics for direct drop-in use.
  • CD74HC165M96 --: Widely available 8-bit parallel-in/serial-out shift register from the HC family, slightly slower than LV but functionally compatible and pin-compatible in many designs.
