Description and Introduction

CMOS Digital Integrated Circuit Silicon Monolithic The TC74AC161FT is a synchronous presettable binary counter manufactured by Toshiba. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range (VCC):** 2.0V to 5.5V  
- **High-Speed Operation:** tpd = 6.0 ns (max) at 5V  
- **Low Power Consumption:** ICC = 4.0 μA (max) at 5V  
- **Output Current:** ±24 mA (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-16  

### **Descriptions:**  
- **Type:** 4-bit synchronous binary counter  
- **Counting Mode:** Synchronous counting with parallel load capability  
- **Clock Input:** Positive-edge triggered  
- **Reset Function:** Asynchronous master reset (MR)  
- **Preset Function:** Parallel load (PE) for preset values  
- **Carry Output:** Ripple carry output (TC) for cascading  

### **Features:**
