2-Bit Bidirectional Voltage Level Translator for Open-Drain and Push-Pull Applications UM2102S SOT23-6 General Description The UM2102S allows bidirectional voltage translations between 1.5V and 5V without the use of a direction pin. The UM2012S is not a bus buffer which provides both level translation and physically isolates the capacitance to either side of the bus when both sides are connected. The UM2102S only isolates both sides when the VREF is connected to GND. Pull-up resistors are required on both sides to provide the logic HIGH levels on the translator’s bus. The size of these pull-up resistors depends on the system. The device is designed to work with Standard-mode,...
