LXB0104

Description

The LXB0104 is a 4-bits bi-directional level translator for push-pull applications which incorporates a buffered architecture with edge rate accelerators (one shots) to improve the overall data rate up to 110Mbps at 3.3V to 5.0V translation. This device is a universal level translator with A port operating from 1.2V to 3.6V (V_CCA) and B port 1.65V to 5.5V (V_CCB). This allows for universal low-voltage bi-directional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes. For proper operation, please be aware V_CCA must not exceed VCCB and the device driving the data I/Os of the LXB0104 must have drive strength of at least ±2mA.

The OE pin is used to activate the device. When OE is HIGH, the translator switch is on. Otherwise, when OE is LOW, the translator switch is off, and a high-impedance OFF-state exists between ports. OE pin is the input for the device and should never be left floating. To ensure the high-impedance OFF-state during power-up or power-down, OE pin should be tied to GND through a pulldown resistor before V_CCA becomes stable, the value of the resistor is recommended to be 10kΩ which is determined by the current-sourcing capability of the driver.

This device is fully specified for partial power-down applications using I_OFF. The I_OFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. This inhibits current backflow into the device which prevents damage to the device. If an external pullup or pulldown resistor is used on the device I/O ports, the resistor values must be larger than 50kΩ to avoid affecting V_OH or V_OL.

Overall, the LXB0104 is designed for easy-to-use with auto direction. So, no need for a direction pin to minimize system effort. This device supports 5V tolerant I/O pins in only translate push-pull CMOS logic output applications.
