NLSX3373
2-Bit 20 Mb/s Dual-Supply
Level Translator
The NLSX3373 is a 2−bit configurable dual−supply bidirectional
auto sensing translator that does not require a directional control pin.
The V_CC I/O and V_L I/O ports are designed to track two different
power supply rails, V_CC and V_L respectively. The V_CC supply rail is
configurable from 1.65 V to 4.5 V while V_L supply rail is
configurable to 1.2 V to 4.1 V. This allows lower voltage logic
signals on the V_L side to be translated into higher voltage logic
signals on the V_CC side, and vice−versa.
The NLSX3373 translator has open−drain outputs with integrated
10 kW pullup resistors on the I/O lines. The integrated pullup
resistors are used to pullup the I/O lines to either V_L or V_CC. The
NLSX3373 is an excellent match for open−drain applications such as
the I²C communication bus.
