- **Mounting Type:** Through Hole  

### **Descriptions:**  
The SN74ALS620AN is an octal bus transceiver designed for asynchronous two-way communication between data buses. It features non-inverting 3-state outputs and is part of the 74ALS logic family, known for low power consumption and high speed.  

### **Features:**  
- **Octal Bus Transceiver:** Allows bidirectional data flow between two buses.  
- **3-State Outputs:** Enables high-impedance state for bus isolation.  
- **Non-Inverting Logic:** Maintains signal polarity.  
- **Wide Operating Voltage:** 4.5V to 5.5V supply range.  
- **High-Speed Operation:** Low propagation delay (12ns max).  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with TTL logic levels.  
- **20-Pin DIP Package:** Through-hole mounting for easy prototyping.  

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

Application Scenarios & Design Considerations

Octal Bus Transceivers

Alternative Part Number

  • 74ALS620AN --: Same 74ALS620 octal bus transceiver function and pinout from an alternate vendor, direct drop-in replacement.
  • DM74ALS620AN --: Equivalent ALS-series octal bus transceiver in DIP package with compatible logic levels and pinout.
  • SN74ALS245AN --: Similar octal bus transceiver with 3-state outputs; usable substitute if inverting function is not required, verify pinout.
  • SN74ABT620N --: Similar octal bus transceiver from TI's ABT family with comparable drive and pinout, usable where slightly faster switching is acceptable.
