Logic Level Translator 14-Pin TDFN EP

The MAX14611 is a quad bidirectional logic-level translator that provides the level shifting necessary to allow data transfer in a multivoltage system. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. A low-voltage logic signal present on the VL side of the device appears as a high-voltage logic signal on the VCC side of the device, and vice-versa. The device is ideal for I²C bus as well as MDIO bus applications where open-drain operation is often required. The device features a three-state output mode (active-low TS). Drive active-low TS high to connect the pullup to the powered I/O port. This allows for continuous, undisrupted I²C operation on the powered side of the device while the level translation function is off. The MAX14611 is a pin-to-pin compatible upgrade to the MAX3378E in the TDFN package. The MAX14611 features enhanced high-electrostatic-discharge (ESD) protection on all I/OVCC_ ports up to ±6kV HBM. The device operates over the -40°C to +85°C extended temperature range and is available in 3mm x 3mm, 14-pin TDFN and 4.9mm x 5.1mm, 14-pin TSSOP packages.
