The RoHS non-compliant designation means it is not certified to the EU RoHS directive; verify your exemption or end-market requirements before specifying.
Within the MAX6734 family, the threshold variants differ by the fixed-voltage options (e.g., other versions monitor 1.8V/3.0V/Adj or 3.3V/5V/Adj). The MAX6734KASVD3-T is the specific variant with 1.575V, 2.925V, and adjustable thresholds. For a different threshold set, check the MAX6734 family ordering guide for the suffix that matches your rail voltages. No single pin-compatible drop-in with different thresholds exists — the thresholds are mask-programmed per variant.
Yes, the open-drain output can be pulled up to 5V, so it interfaces directly with 5V logic. The adjustable third channel can be set to monitor a 5V rail via an external resistor divider. The fixed thresholds (1.575V and 2.925V) are designed for 1.8V and 3.3V rails, not for direct 5V monitoring — use the adjustable channel for 5V supervision.
