Description and Introduction

TRIPLE 3-INPUT POSITIVE-NOR GATES The SN5427J is a quadruple 2-input positive-NAND buffer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** NAND Gate  
- **Number of Circuits:** 4  
- **Number of Inputs per Gate:** 2  
- **Supply Voltage (VCC):** 4.75V to 5.25V (standard TTL levels)  
- **Propagation Delay:** Typically 10ns  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** Ceramic DIP (Dual In-line Package)  
- **Output Type:** Totem Pole  

### **Descriptions:**  
- The SN5427J is a TTL-compatible logic device containing four independent 2-input NAND buffers.  
- It is part of the 5400 series, which is designed for military and industrial applications with a wider temperature range.  
- The device provides high-speed operation and reliable performance in digital logic circuits.  

### **Features:**  
- High noise immunity  
- Standard TTL power dissipation  
- Fan-out of 10 (can drive up to 10 standard TTL inputs)  
- Ceramic package for rugged applications  

This information is based on the original Texas Instruments datasheet for the SN5427J.

Application Scenarios & Design Considerations

TRIPLE 3-INPUT POSITIVE-NOR GATES

Alternative Part Number

  • DM74LS27N --: Triple 3-input NOR gate in the LS family with similar logic function and DIP package, widely available and pin-compatible in most designs.
  • MC14027BCP --: CMOS triple 3-input NOR gate offering lower power consumption and a different series prefix, suitable as a functional replacement with level compatibility checks.
  • CD4027BE --: CMOS logic device from a different series that can serve as an alternative logic building block when exact TTL speed is not critical.
