NLSX4302E
2-Bit 20 Mb/s Dual-Supply
Level Translator
The NLSX4302E is a 2−bit 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. Both the VCC and VL
supply rails are configurable from 1.5 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 vice−versa.
The NLSX4302E translator uses external pull−up resistors on the
I/O lines. The external pull−up resistors are used to pull up the I/O
lines to either VL or VCC. The NLSX4302E is an excellent match for
open−drain applications such as the I2C communication bus.
Features
• VL can be Less than, Greater than or Equal to VCC
• Wide VCC Operating Range: 1.5 V to 5.5 V
Wide VL Operating Range: 1.5 V to 5.5 V
• High−Speed with 20 Mb/s Guaranteed Date Rate
• Low Bit−to−Bit Skew
• Enable Input and I/O Pins are Overvoltage Tolerant (OVT) to 5.5 V
• Non−preferential Powerup Sequencing
• Power−Off Protection
• Small Space Saving Package: 1.4 mm x 1.2 mm UQFN8 Package
• These Devices are Pb−Free and are RoHS Compliant
Typical Applications
• I2C, SMBus
