Description and Introduction

CMOS Digital Integrated Circuit Silicon Monolithic Dual Binary Counter The TC74AC393FT is a dual 4-bit binary ripple counter manufactured by Toshiba. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Logic Family:** AC Series (Advanced CMOS)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **High-Speed Operation:** 4.5 ns (typical) at 5V  
- **Low Power Consumption:** 4 μA (max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP-14  

### **Descriptions:**  
- The TC74AC393FT consists of two independent 4-bit ripple counters.  
- Each counter has a separate clock (CP) input and a reset (MR) input.  
- Outputs change state synchronously on the HIGH-to-LOW clock transition.  

### **Features:**  
- **Dual Counter Configuration:** Two separate 4-bit counters in one package.  
- **Asynchronous Master Reset (MR):** Clears all flip-flops independently.  
- **Wide Operating Voltage:** Compatible with 3.3V and 5V systems.  
- **High Noise Immunity:** CMOS technology ensures reliable performance.  
- **Balanced Propagation Delays:** Ensures consistent timing characteristics.  

This information is based solely on Toshiba's datasheet for the TC74AC393FT.

Application Scenarios & Design Considerations

CMOS Digital Integrated Circuit Silicon Monolithic Dual Binary Counter

Alternative Part Number

  • MC74AC393DT --: Same AC-family dual 4-bit binary counter function in a TSSOP package, widely available and pin-compatible.
  • SN74AC393PW --: AC-logic dual 4-bit counter with equivalent function and TSSOP footprint, good electrical match.
  • CD74AC393M --: AC-family dual 4-bit binary counter, functionally equivalent though in SOIC package requiring layout adjustment.
