Description and Introduction

Synchronous 4-Bit Up/Down Binary Counters 16-CDIP 0 to 70 The SN74S169J is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Synchronous 4-Bit Up/Down Binary Counter  
- **Number of Bits:** 4  
- **Counting Sequence:** Up/Down  
- **Trigger Type:** Positive Edge  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C
