4-Bit Bi-Directional Level Translator Open-Drain and Push-Pull Applications;

The LSF0204 is a 4-channel bidirectional multi-voltage level translator for open-drain and push-pull applications. This device is a universal level translator with A port operating from 0.8V to 4.5V (Vref_A) and B port from 1.8V to 5.5V (Vref_B). This range allows for bidirectional voltage translations between 0.8V and 5.0V. Be aware that Vref_B is recommended to be at 1.0V higher than Vref_A for the best signal integrity.\n\n The EN pin is used to activate the device. When EN is HIGH, the translator switch is on. Otherwise, if EN is LOW, the translator switch is off, and a high-impedance state exists between ports. The EN input circuit is designed to be supplied by Vref_A. EN must be LOW to ensure the high-impedance state during power-up or power-down to avoid misoperation.\n\n Please note that an external Rpu (pullup resistor) is required on port A and B for push-pull and open-drain application because a pull-high state can avoid misoperation during the power sequence. About the Rpu, the smaller value can result in the larger driving current. Overall, the LSF0204 is designed for easy-to-use with auto direction. So, there is no need for a direction pin to minimize system effort. This device supports 5V tolerant I/O pins for compatibility with TTL levels in a variety of applications which require a proper voltage translation.\n\n
