NLSX4373DR2G

NLSX4373DR2G is a 2bit configurable dual-supply bidirectional auto-sensing translator that does not require a directional control pin. The VCC I/O and VL I/O ports are designed to track two different power supply rails, VCC and VL respectively. The VCC supply rail is configurable from 1.5V to 5.5V while the VL supply rail is configurable from 1.5V to 5.5V. This allows voltage logic signals on the VL side to be translated into lower, higher, or equal value voltage logic signals on the VCC side, and vice-versa. The NLSX4373 translator has open-drain outputs with integrated 10Kohm pullup resistors on the I/O lines. The integrated pullup resistors are used to pull up the I/O lines to either VL or VCC. The NLSX4373 is an excellent match for open-drain applications such as the I²C communication bus. Application includes I²C, SMBus, PMBus, low voltage ASIC level translation, mobile phones, PDAs, cameras.

• VL can be less than, greater than or equal to VCC, low bit−to−bit skew
• VCC operating range from 1.5V to 5.5V, VL operating range from 1.5V to 5.5V
• Enable input and I/O lines have overvoltage tolerant (OVT) to 5.5V
• Non-preferential powerup sequencing, integrated 10Kohm pullup resistors
• AEC-Q100 qualified and PPAP capable, VCC supply current is 0.5µA typical
• VL supply current is 0.3µA typical at (I/O VCC and I/O VL unconnected, VEN = VL)
