Description and Introduction

8-Bit Parallel-Out Serial Shift Registers The SN74LV164APWR is a 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Logic Type:** Shift Register  
- **Number of Bits:** 8  
- **Output Type:** Push-Pull  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **High-Level Output Current:** -6 mA  
- **Low-Level Output Current:** 6 mA  
- **Propagation Delay Time:** 13.5 ns (typical at 5 V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** TSSOP-14  
- **Mounting Type:** Surface Mount  
- **Logic Family:** LV (Low-Voltage)  

### **Descriptions:**  
The SN74LV164APWR is an 8-bit serial-in, parallel-out shift register designed for low-voltage operation (2 V to 5.5 V). It features a serial data input (A and B), a clock input (CLK), and a clear input (CLR). Data is shifted into the register on the rising edge of the clock, and the outputs are available in parallel.  

### **Features:**  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **Low Power Consumption:** Optimized for battery-operated devices  
- **High Noise Immunity:** Typical for LV family  
- **Parallel Outputs:** 8-bit parallel output for direct interfacing  
- **Serial Data Inputs:** Two serial inputs (A and B) for flexibility  
- **Asynchronous Clear:** Reset all outputs to low with the CLR input  
- **ESD Protection:** Exceeds 2000 V per JESD 22  

This information is based solely on the technical documentation for the SN74LV164APWR from Texas Instruments.

Application Scenarios & Design Considerations

8-Bit Parallel-Out Serial Shift Registers

Alternative Part Number

  • MC74VHC164DTR2G --: 8-bit serial-in/parallel-out shift register in the same VHC logic family, TSSOP package, direct functional and pin-compatible replacement.
  • 74VHC164FT --: Equivalent 8-bit serial-in/parallel-out shift register with similar VHC speed and drive characteristics, available in TSSOP.
  • 74AHC164PW --: AHC-family 8-bit serial-in/parallel-out shift register in TSSOP, slightly slower but widely available and functionally compatible.
  • SN74AHC164PWR --: Same TI 8-bit shift register in AHC family with similar speed and TSSOP package, usable when slight drive/speed differences are acceptable.
