Key Specifications

The UM2001P is a bidirectional voltage level translator operational from 1.0V to 3.6V (V_CCA) and 1.8V to 5.5V (V_CCB), 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 (R_on) 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. When EN is low, the translator switch is off, and a high-impedance state exists between ports.

The translators provide excellent ESD protection to lower voltage devices, and at the same time protect less ESD-resistant devices.
