Description and Introduction

Synchronous 4-Bit Binary Counter The SN74F161AN is a synchronous 4-bit binary counter manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Series:** 74F  
- **Logic Type:** Synchronous 4-Bit Binary Counter  
- **Operating Voltage:** 4.5V to 5.5V  
- **High-Level Output Current:** -1 mA  
- **Low-Level Output Current:** 20 mA  
- **Propagation Delay Time:** 8.5 ns (typical)  
- **Maximum Clock Frequency:** 100 MHz  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** PDIP-16 (Plastic Dual In-Line Package)  
- **Mounting Type:** Through Hole  

### **Descriptions:**
- The SN74F161AN is a synchronous presettable binary counter with asynchronous clear.  
- It features parallel load capability for preset data entry.  
- The counter advances on the rising edge of the clock signal when enabled.  
- It includes carry look-ahead circuitry for cascading multiple counters.  

### **Features:**
- **Synchronous Counting:** Operation is synchronized with the clock signal.  
- **Parallel Load:** Allows loading of preset values.  
- **Asynchronous Clear:** Resets the counter independently of the clock.  
- **Carry Output:** Facilitates cascading of multiple counters.  
- **High-Speed Operation:** Supports clock frequencies up to 100 MHz.  
- **TTL-Compatible Inputs and Outputs:** Ensures compatibility with TTL logic levels.  

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

Application Scenarios & Design Considerations

Synchronous 4-Bit Binary Counter

Alternative Part Number

  • MC74F161AN --: Same 74F161 synchronous 4-bit binary counter function with identical pinout and F-series speed, direct drop-in replacement.
  • 74F161APC --: Equivalent 74F161 counter in DIP-16 package with matching logic function and timing characteristics.
  • N74F161AN --: Philips/NXP 74F161 synchronous counter, same function and pinout, suitable alternative when TI part is unavailable.
  • 74F161N --: Standard 74F161 4-bit synchronous counter in DIP-16, same logic family and pin configuration, suitable as a functional substitute.
