UM2001P
Bidirectional Voltage Level Translator for Open-Drain and Push-Pull Applications
UM2001P SOT363
General Description
The UM2001P is a bidirectional voltage level translator operational from 1.0V to 3.6V (VCCA) and 1.8V to 5.5V (VCCB), which allows bidirectional voltage translations between 1.0V and 5V without the need for a direction pin in open-drain or push-pull applications. The UM2001P is a 1-bit level translator. Its transmission speeds are below 33MHz for an open-drain system with a 50pF capacitance and a pull-up resistor of 197Ω. The low ON-state resistance (Ron) of the switch allows connections to be made with minimal propagation delay. When EN is high, the translator switch is ON, and the A I/O is connected to the B I/O, allowing bidirectional data flow between ports.
