Description and Introduction

TOSHBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC The TC74ACT273FW is an octal D-type flip-flop manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Logic Family:** ACT (Advanced CMOS Technology)  
- **Number of Bits:** 8 (Octal)  
- **Function:** Positive-edge-triggered D-type flip-flop with clear  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **High-Level Input Voltage (VIH):** 2.0V (min)  
- **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **High-Level Output Current (IOH):** -24mA  
- **Low-Level Output Current (IOL):** 24mA  
- **Propagation Delay Time (tpd):** 10ns (max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOP-20 (Small Outline Package)  

### **Descriptions:**  
- The TC74ACT273FW consists of eight edge-triggered D-type flip-flops with a common clock (CP) and a master reset (MR) input.  
- Data is transferred to the outputs (Q0–Q7) on the positive edge of the clock pulse.  
- A low level on the master reset (MR) clears all flip-flop outputs to a low state, regardless of clock or data inputs.  

### **Features:**  
- **High-Speed Operation:** Compatible with TTL levels and optimized for high-speed performance.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **Wide Operating Voltage:** Supports 4.5V to 5.5V operation.  
- **3-State Outputs:** Not applicable (standard outputs only).  
- **Direct Clear Function:** Asynchronous master reset for immediate output clearing.  
- **Packaging:** SOP-20 (FW package suffix).  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

TOSHBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC

Alternative Part Number

  • 74ACT273SC --: Same 74ACT octal D flip-flop function with async clear, pin-compatible SOIC package, widely available and cost-effective.
  • SN74ACT273DW --: Direct functional equivalent octal D-type flip-flop with clear, same ACT logic family and SOIC-20 footprint.
  • MC74ACT273DWR2G --: Octal D flip-flop with clear in the ACT family, SOIC-20 package, good second-source option with similar speed and drive.
  • 74ACT273MTC --: Same 74ACT273 octal D flip-flop function with async reset, TSSOP package, widely available and pin-compatible replacement.
  • SN74ACT273PW --: Direct functional equivalent octal D-type flip-flop with clear, TSSOP package, from a major logic IC vendor.
  • MC74ACT273DT --: ACT-family octal D flip-flop with asynchronous reset in TSSOP, suitable drop-in alternative for the Toshiba part.
