The F75913 is a 4 bit bidirectional voltage level shifter with Enable (EN) input.

The L port is designed to track VCC (L). VCC (L) accepts any supply voltage from 1.1 V to [V_CC(H)- 0.7 V]. The H port is designed to track V_CC(H). V_CC(H) accept any supply voltage from 1.8V to 3.3V. This allows for universal low-voltage bidirectional translation between any of the 1.2V, 1.5V, 1.8V and 2.5V voltage nodes. V_CC(H) should exceed V_CC(L) over 0.7V.

The F75913 is designed that the EN input circuit is supplied by V_CC(L). When the Enable (EN) input is low, all outputs are placed in the high-impedance state. To ensure the high-impedance state during power up or power down, EN should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
