Level Translator, 4-Bit, Configurable Dual-Supply, 100 Mbps

The NLSX3014 is a 4 bit configurable dual supply bidirectional level translator without a directional control pin. The IOVCC and IOVL ports are designed to track two different power supply rails, VCC and VL respectively. The VCC supply rail is configurable from 1.3V to 4.5V while the VL supply rail is configurable from 0.9V to VCC minus 0.4V. This allows lower voltage logic signals on the VL side to be translated into higher voltage logic signals on the VCC side, and vice versa. Both IO ports are auto sensing and thus, have no direction pin. The Enable EN input, when Low, disables both IO ports by putting them in 3 state. This reduces significantly the supply currents from both VCC and VL. The EN signal is designed to track VL.
