Description and Introduction

Binary/decade up/down counter The MC14029BD is a part from the MC14000B series of integrated circuits, which are CMOS logic devices.  

### **Manufacturer:**  
- **Motorola** (original manufacturer, now part of ON Semiconductor)  

### **Specifications:**  
- **Logic Type:** Binary Counter/Divider  
- **Number of Bits:** 4-bit  
- **Counting Sequence:** Binary or BCD (programmable)  
- **Supply Voltage Range:** 3V to 18V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package Type:** SOIC-16 (Surface Mount)  

### **Descriptions and Features:**  
- **Programmable Counter:** Can be configured as a binary counter or BCD (decade) counter.  
- **Asynchronous Reset:** Includes a master reset (MR) input to clear the counter.  
- **High Noise Immunity:** CMOS technology provides high noise resistance.  
- **Low Power Consumption:** Suitable for battery-operated applications.  
- **Wide Voltage Range:** Operates from 3V to 18V, making it versatile for different logic levels.  
- **Output Drive Capability:** Can drive two low-power TTL loads or one low-power Schottky load over the full voltage range.  

This part is commonly used in frequency division, timing circuits, and digital counting applications.

Application Scenarios & Design Considerations

Binary/decade up/down counter

Alternative Part Number

  • CD4029BE --: Pin-compatible CMOS presettable up/down counter with the same 4029 function, widely available and a direct functional drop-in for the MC14029BD.
  • HEF4029BP --: Equivalent 4000-series presettable up/down counter with matching logic and pinout, suitable as a direct replacement.
  • MC14529B --: Motorola-lineage CMOS counter in the same family, offering similar presettable up/down counting behavior for legacy designs.
  • MC14516BCP --: Similar Motorola/ON 4000-series binary up/down counter in DIP-16; close functional match though pinout should be verified before substitution.
