Description and Introduction

QUADRUPLE 2-INPUT POSITIVE-NOR BUFFERS WITH OPEN-COLLECTOR OUTPUTS The SN5433J is a quad 2-input positive-NAND buffer manufactured by Texas Instruments (TI).  

**Key Specifications:**  
- **Logic Type:** NAND Gate  
- **Number of Circuits:** 4  
- **Number of Inputs:** 2 per gate  
- **Supply Voltage Range:** 4.75V to 5.25V (standard TTL levels)  
- **Operating Temperature Range:** -55°C to +125°C (military-grade)  
- **Package Type:** Ceramic DIP (Dual In-line Package)  
- **Propagation Delay:** Typically 10ns (varies with conditions)  

**Features:**  
- High-speed TTL logic  
- Military-spec reliability  
- Standard pin configuration for compatibility  
- Robust ceramic packaging for harsh environments  

**Description:**  
The SN5433J is part of TI’s 5400 series, designed for military and industrial applications requiring high reliability. It provides four independent NAND gates in a single package, each with two inputs. The device operates on a 5V supply and is built for extended temperature ranges.  

Note: The SN5433J is an older part and may be obsolete or available only through specialty distributors.

Application Scenarios & Design Considerations

QUADRUPLE 2-INPUT POSITIVE-NOR BUFFERS WITH OPEN-COLLECTOR OUTPUTS

Alternative Part Number

  • 74LS33N --: Quad 2-input NOR gate with open-collector outputs, same logic function and pinout as SN5433, in a DIP package; LS TTL is a common functional replacement for the 54-series part.
  • MC74HC33N --: Quad 2-input NOR gate with open-drain outputs in a DIP package, pin-compatible logic equivalent suitable for replacing the SN5433J function.
  • CD74HCT33E --: Quad 2-input NOR gate with open-drain outputs, HCT TTL-compatible inputs, DIP package; a practical alternative when the exact 54-series part is unavailable.
  • 74LS33PC --: Quad 2-input NOR gate with open-collector outputs in DIP, functionally equivalent to SN5433 with standard 74LS series naming.
