Power Supply: Ensure the supply voltage (VDD) is within the specified range of 3.0V to 5.5V.
Isolation Considerations: Do not exceed the maximum isolation voltage (VIORM) of 2.5kV to prevent damage.
Signal Integrity: Account for a propagation delay (tPD) of 14ns to 20ns when designing timing-critical applications.
Common Mode Transient Immunity: The device supports a CMTI of up to 25kV/μs, which should be considered in noisy environments.
Data Transmission: For optimal performance, keep the data rate (fDATA) under 150Mbps.
Power Management: Monitor power consumption; each channel consumes approximately 9mA at quiescent state.
Crosstalk Mitigation: Design layouts to minimize channel-to-channel crosstalk, noting the attenuation of at least 65dB.
