The MAX14611 is a quad bidirectional logic-level translator that provides the level shifting necessary to allow data transfer in a multivoltage system. The device features a three-state output mode and enhanced electrostatic discharge protection.
The MAX14611 provides four independent bidirectional level‑shifting channels, allowing low‑voltage signals on one side to be translated to higher voltages on the other side and vice‑versa. It supports I²C, SPI, and MDIO buses, includes a three‑state output mode for continuous operation, and offers enhanced ESD protection up to +6 kV.
The device operates over a wide temperature range (‑40 °C to +85 °C) and is offered in compact 14‑pin TDFN‑EP and TSSOP packages. Electrical specifications include supply ranges of 0.9‑5 V (VL) and 1.65‑5.5 V (VCC), internal pull‑up resistors of 10 kΩ, and data rates up to 500 kbps (open‑drain) or 8 Mbps (push‑pull).
