NLSX5012: Level Translator, 2-Bit, 140 Mbps, Enhanced Dual-Supply, Auto Sense

The NLSX5012 is a 2-bit configurable dua-supply autosensing bidiretional 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 0.9V to 4.5V. This allows a logic signal on the VL side to be translated to either a higher or a lower logic voltage on the Vcd side, and vice-versa.The NLSX5012 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.The NLSX5012 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 NLSX5012 is that each I/O VLn and I/O VCCn channel cna function as either an input or an output.An Output Enable (EN) input is available 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 current from both VCC and VL. The EN signal is referenced to the VL supply.
