Description and Introduction

Synchronous 4-Bit Up/Down Counters (Dual Clock With Clear) The SN54192J is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Synchronous 4-Bit Up/Down Counter  
- **Count Sequence:** Up or Down (Programmable)  
- **Operating Voltage:** 4.5V to 5.5V  
- **Clock Frequency:** Typically up to 25 MHz  
- **Output Type:** TTL (Transistor-Transistor Logic)  
- **Number of Bits:** 4  
- **Reset Function:** Asynchronous Master Reset (MR)  
- **Load Function:** Parallel Load Capability  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Package Type:** Ceramic DIP (Dual In-line Package)  

### **Descriptions:**  
- The SN54192J is a high-speed synchronous counter with individual preset inputs for each flip-flop.  
- It features separate up and down clock inputs for bidirectional counting.  
- The counter can be cleared asynchronously using the Master Reset (MR) pin.  
- It includes carry and borrow outputs for cascading multiple counters.  

### **Features:**  
- **Synchronous Operation:** All flip-flops change state simultaneously.  
- **Programmable Count Direction:** Selectable up or down counting.  
- **Parallel Load Capability:** Allows presetting the counter to a desired value.  
- **Asynchronous Master Reset:** Clears all outputs regardless of clock state.  
- **Carry/Borrow Outputs:** Facilitates cascading multiple counters.  
- **High-Speed TTL Compatibility:** Suitable for high-performance digital systems.  

This information is based on the manufacturer's datasheet for the SN54192J.

Application Scenarios & Design Considerations

Synchronous 4-Bit Up/Down Counters (Dual Clock With Clear)

Alternative Part Number

  • MC54192L --: Same 54192 decade counter function in the 54xx military temperature series, direct functional equivalent with different prefix.
  • DM54192J --: Pin-compatible 54192 up/down decade counter in ceramic DIP, widely used as a second source.
  • CD54192J --: Equivalent 54192 counter in the CD54 series, suitable replacement for military-grade applications.
  • MC10192L --: Equivalent 4-bit up/down decade counter in the same 10K/100K ECL logic family, pin-compatible DIP package.
  • F10192DC --: Direct functional replacement for the 54192 decade counter, same ECL logic family and DIP pinout.
  • CD40192BE --: CMOS 4-bit up/down decade counter with similar counting function, usable where ECL speed is not critical.
