Overview
The NLSX3014, produced by onsemi, is a 4-bit configurable dual-supply bidirectional level translator. This device is designed to translate logic signals between two different power supply rails, VCC and VL, without the need for a direction control pin. The VCC supply rail can be configured from 1.3 V to 4.5 V, while the VL supply rail ranges from 0.9 V to (VCC - 0.4) V. This allows for seamless translation of lower voltage logic signals on the VL side to higher voltage logic signals on the VCC side and vice versa. The device features an Output Enable (EN) input that, when set low, disables both I/O ports and reduces supply currents significantly.

Q & A
- What is the primary function of the NLSX3014?
The NLSX3014 is a 4-bit configurable dual-supply bidirectional level translator that translates logic signals between two different power supply rails, VCC and VL.
- What are the operating voltage ranges for VCC and VL?
VCC can be configured from 1.3 V to 4.5 V, and VL ranges from 0.9 V to (VCC - 0.4) V.
- What is the maximum data rate supported by the NLSX3014?
The device supports a maximum data rate of 100 Mb/s for VL > 1.6 V.
- How does the Output Enable (EN) pin function?
The EN pin, when set low, disables both I/O ports and puts them in a high-impedance state, significantly reducing power consumption.
- What are the key features of the NLSX3014?
Key features include a wide operating voltage range, high-speed data rate, low bit-to-bit skew, overvoltage tolerant pins, non-preferential powerup sequencing, and small packaging.
- What types of devices typically use the NLSX3014?
The NLSX3014 is typically used in mobile phones, PDAs, and other portable devices.
- Is the NLSX3014 a Pb-Free device?
- What is the package size of the NLSX3014?
The device comes in a small 1.7 mm x 2.0 mm UQFN12 package.
- Does the NLSX3014 require a direction control pin?
No, the NLSX3014 does not require a direction control pin as it auto-senses the direction of data flow.
- What is the operating temperature range of the NLSX3014?
The operating temperature range is from -40°C to +85°C.
