Q & A
- What is the operating voltage range for VCC and VL in the NLVSX4014MUTAG?
VCC operates from 1.3 V to 4.5 V, and VL operates from 0.9 V to (VCC - 0.4) V.
- What is the maximum data rate supported by the NLVSX4014MUTAG?
The device supports a data rate of up to 100 Mb/s for VL > 1.6 V.
- Does the NLVSX4014MUTAG require a direction control pin?
No, the device has auto-sensing I/O ports and does not require a direction control pin.
- What is the package type and dimensions of the NLVSX4014MUTAG?
The device comes in a UQFN12 package with dimensions 1.7 mm x 2.0 mm.
- Is the NLVSX4014MUTAG suitable for automotive applications?
Yes, it is AEC-Q100 qualified and PPAP capable, making it suitable for automotive and other demanding applications.
- How does the Enable (EN) pin function in the NLVSX4014MUTAG?
The EN pin, when driven low, disables both I/O ports by putting them in a high impedance state, minimizing power consumption.
- What are the recommended power supply guidelines for the NLVSX4014MUTAG?
The VL supply should be less than or equal to (VCC - 0.4) V. Decoupling capacitors (0.01 to 0.1 μF) should be used on the VL and VCC power supply pins.
- Can the NLVSX4014MUTAG be used as a uni-directional translator?
Yes, the device can function as a non-inverting uni-directional translator, allowing each I/O pin to be configured as either an input or output.
- What kind of load should be driven by the NLVSX4014MUTAG?
The device is designed to drive CMOS inputs. Resistive pullup or pulldown loads of less than 50 kΩ should not be used.
- Is the NLVSX4014MUTAG protected against overvoltage conditions?
Yes, the device has overvoltage tolerant (OVT) protection on the Enable and I/O pins.
