Instructions for SN75C189N

1. Power Supply Connection:

   • Connect the VCC pin to a stable 5V power supply.
   • Ensure that the ground (GND) pin is properly connected to the system ground.

2. Input Signal Handling:

   • Apply input signals within the specified voltage range to avoid damage or incorrect operation.
   • Ensure that input signals are compatible with the logic levels of the device.

3. Output Load Considerations:

   • The output can drive loads up to the specified current limits without exceeding the maximum power dissipation.
   • Use external resistors if necessary to limit current and protect the device.

4. Operating Temperature:

   • Operate the device within the specified temperature range to ensure reliable performance.
   • Provide adequate heat sinking if operating near the upper temperature limit.

5. Handling Static Electricity:

   • Handle the device with care to prevent damage from static electricity.
   • Follow proper ESD handling procedures during installation and testing.

6. Storage Conditions:

   • Store the device in a dry environment within the specified storage temperature range.
   • Avoid exposing the device to excessive humidity or corrosive environments.
