Description and Introduction

Synchronous 4-Bit Up/Down Counters (Dual Clock With Clear) 16-CDIP -55 to 125 The SN54193J is a 4-bit synchronous up/down binary counter manufactured by Texas Instruments (TM). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Synchronous Up/Down Binary Counter  
- **Number of Bits:** 4  
- **Supply Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package Type:** CDIP (Ceramic Dual In-line Package)  
- **Counting Modes:** Up, Down  
- **Clock Input:** Positive-edge triggered  
- **Load & Clear Capabilities:** Asynchronous parallel load and clear inputs  
- **Output Type:** Standard (TTL-compatible)  

### **Descriptions:**  
- The SN54193J is a high-speed 4-bit synchronous counter that can operate in both up and down counting modes.  
- It features separate clock inputs for up (CPU) and down (CPD) counting.  
- Includes asynchronous clear (CLR) and load (LOAD) functions for control flexibility.  
- Designed for military and industrial applications due to its wide temperature range.  

### **Features:**  
- **Synchronous Counting:** Ensures all flip-flops change state simultaneously.  
- **Dual Clock Inputs:** Separate clock inputs for up and down counting.  
- **Asynchronous Clear & Load:** Allows immediate reset or preset of the counter.  
- **Carry & Borrow Outputs:** Provides ripple clock outputs for cascading multiple counters.  
- **High-Speed Operation:** Suitable for fast counting applications.  
- **TTL-Compatible:** Works with standard TTL logic levels.  

This information is based solely on the manufacturer's datasheet for the SN54193J.

Application Scenarios & Design Considerations

Synchronous 4-Bit Up/Down Counters (Dual Clock With Clear) 16-CDIP -55 to 125

Alternative Part Number

  • MC54193L --: Direct functional equivalent 4-bit up/down counter in the same 54193 family, available in ceramic DIP package.
  • DM74193N --: Pin-compatible 4-bit up/down counter with similar logic, widely available and commonly used as a drop-in replacement.
  • CD74HC193E --: CMOS 4-bit up/down counter with equivalent function and pinout, offering lower power consumption as a modern alternative.
  • CD40193BE --: CMOS 4-bit up/down binary counter with the same function and pinout family as the SN54193; lower power and widely available, though it is a CMOS rather than TTL device.
  • 74LS193N --: TTL-compatible 4-bit up/down counter with synchronous clear and load, functionally equivalent to the SN54193 and commonly used as a direct replacement in 5V systems.
  • MC74HC193AN --: High-speed CMOS 4-bit synchronous up/down counter with the same control inputs and pin arrangement, suitable as a functional substitute when CMOS logic levels are acceptable.
  • MC14516BCP --: CMOS presettable 4-bit up/down binary counter offering equivalent counting and preset logic, suitable as a functional replacement in most designs.
  • 74HC193N --: High-speed CMOS 4-bit synchronous up/down binary counter with preset and clear, functionally similar to the SN54193 and easy to source.
