Description and Introduction

DECADE COUNTER; DIVIDE-BY-TWELVE COUNTER; 4-BIT BINARY COUNTER The SN74LS92D is a 4-bit ripple counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Function:** Divide-by-2 and Divide-by-12 Counter  
- **Operating Voltage:** 4.75V to 5.25V  
- **Clock Input:** Two clock inputs (CP1 and CP2)  
- **Outputs:** Four outputs (Q0, Q1, Q2, Q3)  
- **Propagation Delay:** Typically 30 ns  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** SOIC (D)  

### **Descriptions:**  
- The SN74LS92D is a ripple counter that can be configured as a divide-by-2 or divide-by-12 counter.  
- It consists of four master-slave flip-flops internally connected to provide the counting function.  
- The counter can be reset asynchronously via a Master Reset (MR) input.  

### **Features:**  
- **Asynchronous Master Reset:** Clears all flip-flops to zero.  
- **High-Speed Operation:** Suitable for timing and frequency division applications.  
- **Low Power Consumption:** Typical power dissipation of 45 mW.  
- **TTL-Compatible Inputs and Outputs:** Ensures compatibility with other TTL logic devices.  
- **Wide Operating Voltage Range:** Supports standard 5V logic levels.  

This information is based solely on the manufacturer's datasheet for the SN74LS92D.

Application Scenarios & Design Considerations

DECADE COUNTER; DIVIDE-BY-TWELVE COUNTER; 4-BIT BINARY COUNTER

Alternative Part Number

  • DM74LS92N --: Same LS92 divide-by-twelve counter function in a different series prefix, widely available and pin-compatible in DIP form.
  • MC74LS92DR2G --: Direct functional equivalent LS92 counter from a different manufacturer series, suitable drop-in replacement for the logic function.
  • CD74HC92E --: CMOS HC-series divide-by-twelve counter offering similar counting function with lower power, though check supply voltage and drive compatibility.
  • 74LS92PC --: Direct functional equivalent divide-by-twelve counter in the 74LS family, different naming prefix makes it easy to distinguish from the source.
  • MC74LS92N --: Equivalent LS TTL counter from the successor of Motorola's logic line, same electrical characteristics and pin configuration.
