2-Bit 20 Mb/s Dual-Supply Level Translator

The NLSX0102 is a 2-bit configurable dual-supply bidirectional auto sensing translator that does not require a directional 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 VL supply rails are 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 loigc signals on the VCC side, and vice-versa. The NLSX0102 translator has integrated 10k ohms pull-up resistors on the IO lines. The integrated resistors are used to pull-up the IO lines to either VL or VCC. The NLSX0102 is an excellent match for open-drain applications such as the I2C communication bus.
