Description and Introduction

Parallel-Load 8-Bit Shift Registers The SN54166J is a parallel-load 8-bit shift register manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Logic Type:** Shift Register  
- **Number of Bits:** 8  
- **Logic Family:** TTL (Transistor-Transistor Logic)  
- **Supply Voltage (Vcc):** 4.75V to 5.25V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Package Type:** CDIP (Ceramic Dual In-line Package)  
- **Output Type:** Standard (TTL-Compatible)  
- **Propagation Delay:** Typically 30ns (varies with conditions)  
- **Power Consumption:** Moderate (depends on operating conditions)  

### **Descriptions:**
- The SN54166J is a parallel-in/serial-out shift register with synchronous or asynchronous load capability.  
- It features a serial input (DS) and parallel inputs (D0-D7) for flexible data loading.  
- Includes clock (CP), shift/load (SH/LD), and master reset (MR) control inputs.  
- Designed for military and industrial applications due to its wide temperature range.  

### **Features:**
- **Parallel-to-Serial Conversion:** Loads 8-bit data in parallel and shifts it out serially.  
- **Synchronous/Asynchronous Operation:** Supports both modes via the SH/LD input.  
- **Master Reset (MR):** Clears the register asynchronously when activated.  
- **Wide Operating Temperature:** Suitable for harsh environments.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic circuits.  
- **High-Speed Operation:** Fast data shifting with low propagation delay.  

This information is strictly based on the device's datasheet and manufacturer specifications.
