Description and Introduction

Synchronous 4-Bit Up/Down Binary Counters The SN54S169J is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Synchronous 4-Bit Up/Down Binary Counter  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Package Type:** Ceramic DIP (Dual In-Line Package)  
- **Number of Pins:** 16  
- **Counting Sequence:** Binary (Up or Down)  
- **Clock Frequency:** Typically up to 32 MHz  
- **Output Type:** TTL (Transistor-Transistor Logic)  
- **Propagation Delay:** 15 ns (typical)  

### **Descriptions:**  
- The SN54S169J is a high-speed synchronous counter with parallel load capability.  
- It operates in either up or down counting modes based on control inputs.  
- Features synchronous counting and loading for precise timing control.  
- Designed for military and aerospace applications due to its rugged construction.  

### **Features:**  
- Synchronous operation for reduced output skew.  
- Parallel load capability for preset values.  
- Two count-enable inputs for flexible cascading.  
- Carry output for easy expansion to higher-bit counters.  
- Fully buffered clock and control inputs.  
- TTL-compatible inputs and outputs.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Synchronous 4-Bit Up/Down Binary Counters

Alternative Part Number

  • 74S169PC --: Same 4-bit synchronous up/down counter function in a DIP package, pin-compatible with the SN54S169J.
  • MC10H169L --: Equivalent 4-bit synchronous binary up/down counter with similar logic family characteristics and DIP package.
  • DM74S169N --: Direct functional replacement for the 4-bit synchronous up/down counter, widely available in a standard DIP package.
  • MC74S169N --: Pin-compatible 4-bit synchronous up/down counter from the 74S logic family, suitable replacement for the military-grade SN54S169J in commercial applications.
