Description and Introduction

4-BIT SYNCHRONOUS UP/DOWN COUNTERS DUAL CLOCK WITH CLEAR The SN74HC193NSR 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 SN74HC193NSR is a high-speed CMOS logic counter with separate up/down clocks.  
- It features asynchronous parallel load and clear inputs for flexible control.  
- The counter operates synchronously, meaning outputs change on the clock edge.  

### **Features:**  
- **Synchronous Counting:** Controlled by separate up/down clock inputs.  
- **Asynchronous Features:** Parallel load and clear functions.  
- **Carry and Borrow Outputs:** Facilitates cascading multiple counters.  
- **Wide Operating Voltage:** Supports 2V to 6V operation.  
- **Low Power Consumption:** Typical ICC of 80 µA.  
- **Balanced Propagation Delays:** Ensures reliable performance.  

This information is based on TI's official datasheet for the SN74HC193NSR.
