LSF0204T14-13

Translators, Level Shifters Overview

The LSF0204T14-13 is a 4-channel bidirectional multi-voltage level translator designed for open-drain and push-pull applications. It operates with Port A at 0.8V to 4.5V (Vref_A) and Port B at 1.8V to 5.5V (Vref_B). The device supports translation between 0.8V and 5.0V, featuring an active-high enable pin (EN) that controls the switch state. It provides up to 128mA continuous channel current and includes ESD protection exceeding 2000V HBM and 1000V CDM. The component is specified from -40°C to +125°C and utilizes TSSOP-14 packaging.

Translators, Level Shifters FAQ

How does the EN pin function during power-up or power-down?

The EN input circuit is supplied by Vref_A. To ensure a high-impedance state and avoid misoperation during power transitions, EN must be held LOW until Vref_A is stable.

What is the recommended relationship between Vref_A and Vref_B?

For best signal integrity, Vref_B is recommended to be at least 1.0V higher than Vref_A.
