Description and Introduction

RAD-HARD QUAD 2-INPUT OR GATE The **M54HC32K1** is a high-speed CMOS quad 2-input OR gate manufactured by **STMicroelectronics (ST)**. Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Technology:** High-Speed CMOS (HC)  
- **Supply Voltage Range:** 2V to 6V  
- **Input Voltage (High Level, VIH):** 3.15V (min) at VCC = 4.5V  
- **Input Voltage (Low Level, VIL):** 1.35V (max) at VCC = 4.5V  
- **Output Current (High Level, IOH):** -4mA at VCC = 4.5V  
- **Output Current (Low Level, IOL):** 4mA at VCC = 4.5V  
- **Propagation Delay (tPD):** 10ns (typ) at VCC = 4.5V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Package:** Ceramic DIP (Dual In-line Package)  

### **Description:**  
- The **M54HC32K1** is a radiation-hardened, high-reliability device designed for aerospace and military applications.  
- It contains four independent **2-input OR gates** in a single package.  
- Compatible with standard **CMOS** and **TTL** logic levels.  

### **Features:**  
- **Radiation Hardened:** Suitable for space and harsh environments.  
- **Low Power Consumption:** Static current typically <1µA.  
- **High Noise Immunity:** CMOS technology ensures robust performance.  
- **Wide Operating Voltage:** Supports 2V to 6V operation.  
- **High-Speed Operation:** Propagation delay as low as 10ns.  
- **Military Temperature Range:** -55°C to +125°C.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

RAD-HARD QUAD 2-INPUT OR GATE

Alternative Part Number

  • SN74HC32N --: Quad 2-input OR gate in the same HC logic family with matching function and pinout, widely available and a direct functional drop-in.
  • CD74HC32E --: HC-series quad 2-input OR gate with equivalent logic function and compatible electrical characteristics, suitable as a second-source replacement.
  • MC74HC32AN --: Quad 2-input OR gate from the HC family offering the same logic function and similar supply voltage range, usable as an alternative when the original is unavailable.
