Description and Introduction

BCD TO 7-SEGMENT DECODER The SN74LS48N is a BCD-to-7-segment decoder/driver manufactured by **MOT (Motorola)**.  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Function:** BCD-to-7-segment decoder/driver  
- **Output Type:** Open-collector (requires external resistors for LED driving)  
- **Supply Voltage (Vcc):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 16-pin DIP (Dual In-line Package)  
- **Propagation Delay:** Typically 25ns  
- **Power Dissipation:** 45mW (typical)  

### **Descriptions:**  
- Converts 4-bit Binary-Coded Decimal (BCD) input into 7-segment LED display outputs.  
- Includes internal ripple-blanking input/output for display control.  
- Features lamp test and blanking inputs for testing and display management.  

### **Features:**  
- **Active-Low Outputs:** Suitable for common-anode 7-segment displays.  
- **Lamp Test (LT) Input:** Allows all segments to be illuminated for testing.  
- **Ripple Blanking (RBI & RBO):** Used for leading/trailing zero suppression.  
- **High Noise Immunity:** Typical of LS TTL logic.  

This device is commonly used in digital display applications such as counters, clocks, and instrumentation panels.

Application Scenarios & Design Considerations

BCD TO 7-SEGMENT DECODER

Alternative Part Number

  • DM74LS48N --: Same 74LS48 BCD-to-7-segment decoder function in a standard DIP-16 package, directly interchangeable pin-for-pin.
  • MC74LS48N --: Motorola's own 74LS48 decoder in DIP-16, identical logic function and pinout, good drop-in replacement.
  • CD74HC48E --: CMOS 74HC48 BCD-to-7-segment decoder in DIP-16 with same function and pinout; lower power but check logic-level compatibility.
  • SN7448N --: Standard TTL version of the same BCD-to-7-segment decoder/driver; functionally compatible but slightly higher power consumption, acceptable where LS speed is not critical.
