The NLSX5014 is a 4-bit configurable dual-supply autosensing bidirectional level translator that does not require a direction control pin. The IO Vcc- and IO VL-ports are designed to track two different power supply rails, VCC and VL respectively. Both the VCC and the VL supply rails are configurabel 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 NLSX5014 offers the feature that the values of the VCC and VL supplies are indenpendent. 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. The NLSX5014 has high output current capability, which allows the translator to drive high capacitive loads such as most high frequency EMI filters. Another feature of the NLSX5014 is that each IO_VLn and IO_VCCn channel can function as either an input or an output. An Output Enable (EN) input is avaialbe to reduce the power consumption. The EN pin can be used to disable both I/O ports by putting them in 3-state which significantly reduces the supply.
