LSF0204 4-BIT BI-DIRECTIONAL LEVEL TRANSLATOR OPEN-DRAIN AND PUSH-PULL APPLICATIONS Description The LSF0204 is a 4-channel bi-directional 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 bi-directional 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. Pin Assignments 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.
