NLSX4378
4-Bit 20 Mb/s Dual-Supply
Level Translator
The NLSX4378 is a 4âbit configurable dualâsupply 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 1.65 V to 5.5 V while VL supply rail is
configurable to 1.65 V to 5.5 V. 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 viceâversa.
The NLSX4378 translator has openâdrain 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 VL or VCC. The
NLSX4378 is an excellent match for openâdrain applications such as
the I2C communication bus.
