- Common-mode transient immunity (CMTI) is rated at 25 kV/μs.
Timing Parameters:
- The propagation delay time (tpd) is between 30 ns and 60 ns under typical conditions.
- Pulse width distortion (tskew) should be within ±5 ns.
Output:
- The maximum output current (IO) is 15 mA.
Temperature:
- Store the device in temperatures ranging from -40°C to 125°C.
- Operate the device within the temperature range of -40°C to 85°C.
Handling:
- Handle with care to avoid damage from electrostatic discharge (ESD).
- Follow standard soldering procedures to ensure reliable connections.
Mounting:
- Ensure proper orientation and alignment during PCB assembly.
