LXB0104Q

Description

The LXB0104Q is an automotive 4-bits bi-directional level shifter for push-pull applications which incorporates a buffered architecture and edge rate accelerators (one shots) to improve the speed up to 100Mbps 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.

The output-enable (OE) input circuit is designed to be supplied by V_CCA and when the output-enable (OE) input is low, all outputs are placed in the high-impedance state. To ensure the high-impedance state during power-up or power-down, OE should be tied to GND through a pulldown resistor. The minimum value of the pulldown resistor to ground is determined by the current-sourcing capability of the driver which is recommended to be 10kΩ.

For proper operations, V_CCA must not exceed V_CCB and the device driving the data I/Os of the LXB0104Q must be at least ±2mA. If an external pullup or pulldown resistor is applied on the device I/O ports, the resistor values must be larger than 50kΩ to avoid affecting VOH or VOL.

The LXB0104Q is available in TSSOP-14 and U-QFN1720-12 (Type CJ) packages where U-QFN1720-12 (Type CJ) is only 1.7mm x 2.0mm x 0.55mm. The main benefit of this package is most apparent in small portable electronic devices, especially the space-constraint applications. The operation temperature is specified from -40°C to +125°C.
