Description and Introduction

4-BIT SYNCHRONOUS UP/DOWN BINARY COUNTERS The SN74HC191NSR is a 4-bit synchronous up/down binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Synchronous Up/Down Counter  
- **Number of Bits:** 4  
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Output Current:** -5.2 mA  
- **Low-Level Output Current:** 5.2 mA  
- **Propagation Delay Time:** 22 ns (typical) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16 (NSR)  

### **Descriptions:**  
- The SN74HC191NSR is a high-speed CMOS logic device.  
- It features synchronous counting with parallel load capability.  
- It operates in either up or down mode based on control inputs.  
- Includes ripple clock output for cascading multiple counters.  

### **Features:**  
- **Synchronous Counting:** All flip-flops are clocked simultaneously.  
- **Parallel Load:** Allows presetting the counter to any value.  
- **Up/Down Control:** Selectable count direction via a single input.  
- **Ripple Clock Output:** Enables cascading without additional logic.  
- **Low Power Consumption:** CMOS technology ensures minimal power usage.  
- **Wide Operating Voltage:** Supports 2V to 6V operation.
