Description and Introduction

Synchronous 4-Bit Up/Down Binary Counters The SNJ54LS169BJ is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Bits:** 4  
- **Counting Sequence:** Up/Down  
- **Synchronous Operation:** Yes  
- **Operating Voltage:** 4.5V to 5.5V  
- **Maximum Clock Frequency:** 25 MHz (typical)  
- **Output Type:** Standard  
- **Package Type:** Ceramic DIP (Dual In-Line Package)  
- **Operating Temperature Range:** -55°C to +125°C (Military-grade)  

### **Descriptions and Features:**  
- **Up/Down Counting:** Can count up or down based on control inputs.  
- **Parallel Load Capability:** Allows presetting the counter via parallel data inputs.  
- **Synchronous Operation:** All flip-flops change state simultaneously with the clock pulse.  
- **Carry Output:** Provides ripple carry for cascading multiple counters.  
- **Military-Grade Reliability:** Designed for harsh environments with extended temperature range.  
- **Low Power Consumption:** Benefits from the LS (Low-Power Schottky) technology.  

This device is commonly used in military and aerospace applications due to its rugged construction and reliability.

Application Scenarios & Design Considerations

Synchronous 4-Bit Up/Down Binary Counters

Alternative Part Number

  • 74LS169B --: Same 4-bit synchronous up/down binary counter function with identical LS TTL logic family and pinout, widely available from a different vendor.
  • DM74LS169AN --: Direct functional equivalent 4-bit up/down counter in the 74LS family, different naming series and manufacturer, suitable drop-in replacement in most designs.
  • SN74LS169BN --: Commercial-grade version of the same counter from TI with identical logic and pinout; differs from the military J-grade source in temperature range and package.
