General Description

The MAX3394E/MAX3395E/MAX3396E bidirectional level translators provide level shifting required for data transfer in a multivoltage system. Internal slew-rate enhancement circuitry features 10mA current-sink and 15mA current-source drivers to isolate capacitive loads from lower current drivers. In open-drain systems, slew rate enhancement enables fast data rates with larger pullup resistors and increased bus load capacitance. Externally applied voltages, VCC and VL, set the logic high levels for the device. A logic-low signal on one I/O side of the device appears as a logic-low signal on the opposite I/O side, and vice-versa. Each I/O line is pulled up to VCC or VL by an internal pullup resistor, allowing the devices to be driven by either push-pull or open-drain drivers.
