It supports a data rate of 1Mbps with unidirectional channel configuration (2 inputs on side 1, 0 on side 2). ## Industrial temperature range and propagation delay Propagation delay is 130ns max (both tpLH and tpHL), with pulse-width distortion held to 20ns max — tight enough for most SPI and UART isolation links at 1Mbps. Rise and fall times are symmetrical at 20ns typical, which keeps signal integrity clean without excessive edge-rate ringing. ## Common-mode transient immunity — 50kV/µs The common-mode transient immunity (CMTI) is rated at 50kV/µs typical, a key parameter when the isolator sits across a switching power stage or inverter bridge. Fast voltage slew rates on the isolated side can couple through parasitic capacitance and corrupt data; a 50kV/µs CMTI means the part holds its logic state through those edges. For motor-drive or solar-inverter designs, this rating is what keeps the communication link reliable.","metaTitle":"MAX22518AWA+ Digital Isolator, 3500Vrms, 1Mbps, 8-SOIC","metaDescription":"MAX22518AWA+ dual-channel capacitive isolator, 3500Vrms isolation, 1Mbps data rate, -40°C to 125°C.
