Description and Introduction

8-Bit PIPO Shift Register with Asynchronous Clear The TC74HC299AP is an 8-bit universal shift/storage register manufactured by Toshiba. Below are its specifications, descriptions, and features:

### **Manufacturer:**  
Toshiba  

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Input Voltage (Min):** 2V  
- **Low-Level Input Voltage (Max):** 0.8V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** DIP-20  
- **Output Current:** ±5.2mA (at 4.5V)  
- **Propagation Delay:** 14ns (Typical at 5V)  
- **Power Dissipation:** 500mW (Max)  

### **Descriptions:**  
The TC74HC299AP is an 8-bit universal shift register with parallel inputs/outputs and three-state outputs. It can perform parallel load, shift left, shift right, and hold operations. The device is compatible with TTL levels and operates at high speed with low power consumption.  

### **Features:**  
- **8-bit universal shift/storage register**  
- **Parallel and serial input/output capability**  
- **Three-state outputs for bus-oriented applications**  
- **Four operating modes:**  
  - Shift left  
  - Shift right  
  - Parallel load  
  - Hold (no change)  
- **Low power consumption (CMOS technology)**  
- **High noise immunity**  
- **TTL-compatible inputs**  
- **Wide operating voltage range (2V to 6V)**  

This information is based on Toshiba's official datasheet for the TC74HC299AP.

Application Scenarios & Design Considerations

8-Bit PIPO Shift Register with Asynchronous Clear

Alternative Part Number

  • SN74HC299N --: Direct functional equivalent 8-bit universal shift register with 3-state outputs in the same HC logic family and DIP package.
  • CD74HC299E --: Pin-compatible HC-series 8-bit universal shift register with 3-state outputs, widely available as a drop-in replacement.
  • MC74HC299N --: Same HC logic family universal shift register with 3-state outputs in DIP, suitable electrical and functional substitute.
  • MC74HC299AN --: Motorola/ON HC299 universal shift register offering the same 8-bit parallel/serial operation and pinout, a valid alternate source for the Toshiba part.
