The NLSX5011 is a 1-bit configurable dual-supply autosensing bidirectional level translator that does not require a direction control pin. The I/O VCC- and I/O VL-ports are designed to track two different power supply rails, VCC and VL respectively. Both the VCC and the VL supply rails are configurable from 0.9 V to 4.5 V. This allows a logic signal on the VL side to be translated to either a higher or a lower logic signal voltage on the VCC side, and vice-versa. The NLSX5011 offers the feature that the values of the VCC and VL supplies are independent. Design flexibility is maximized because VL can be set to a value either greater than or less than the VCC supply. In contrast, the majority of competitive auto sense translators have a restriction that the value of the VL supply must be equal to less than (VCC - 0.4) V.
