Description and Introduction

INVERTING HEX BUS BUFFER (3-STATE) The M74HC368B1R is a hex inverting buffer/line driver with 3-state outputs, manufactured by SGS (now part of STMicroelectronics).  

### **Specifications:**  
- **Technology:** High-Speed CMOS (HC)  
- **Supply Voltage Range:** 2V to 6V  
- **High Noise Immunity:** CMOS level  
- **Output Drive Capability:** 10 LSTTL loads  
- **Low Power Consumption:** 20μA (max)  
- **Propagation Delay:** 13ns (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin DIP (Dual In-line Package)  

### **Descriptions and Features:**  
- **Hex Inverting Buffer/Line Driver:** Contains six inverting buffers with 3-state outputs.  
- **3-State Outputs:** Allows multiple devices to share a common bus without interference.  
- **Wide Operating Voltage:** Compatible with both TTL and CMOS logic levels.  
- **Balanced Propagation Delays:** Ensures consistent signal timing.  
- **High Output Current:** Suitable for driving bus lines or heavy loads.  
- **ESD Protection:** Improved robustness against electrostatic discharge.  

This IC is commonly used in bus-oriented systems, memory interfacing, and general logic applications requiring signal inversion and buffering.

Application Scenarios & Design Considerations

INVERTING HEX BUS BUFFER (3-STATE)

Alternative Part Number

  • CD74HC368E --: Same HC-family hex buffer/line driver with 3-state inverting outputs, pin-compatible DIP package, direct functional equivalent.
  • MC74HC368AN --: HC-series hex 3-state inverting buffer/line driver matching the original logic function and pinout, widely available alternative.
  • SN74HC368N --: Standard 74HC368 hex buffer with 3-state inverting outputs, same electrical characteristics and DIP footprint for drop-in use.
