Description and Introduction

Synchronous 4-Bit Binary Counters The SN74ALS161BN is a synchronous 4-bit binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Synchronous 4-Bit Binary Counter  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** PDIP-16 (Plastic Dual In-Line Package)  
- **Counting Sequence:** Binary (0000 to 1111)  
- **Clock Frequency:** Up to 32 MHz (typical)  
- **Output Type:** Standard (TTL-Compatible)  
- **Features Parallel Load, Clear, and Count Enable Controls**  
- **Propagation Delay:** 15 ns (typical)  

### **Descriptions and Features:**  
- **Synchronous Operation:** All flip-flops are clocked simultaneously.  
- **Parallel Load Capability:** Allows loading of a preset value into the counter.  
- **Asynchronous Clear:** Resets the counter to zero independently of the clock.  
- **Count Enable Inputs (P and T):** Control counting and cascading operations.  
- **Carry Output (RCO):** Provides a ripple carry signal for cascading multiple counters.  
- **Fully Buffered Outputs:** Ensures minimal loading effects on the clock and control inputs.  
- **Wide Operating Voltage:** Compatible with standard TTL logic levels.  

This IC is commonly used in digital counting applications, frequency division, and sequential logic circuits.
