Overview
The NLSV1T34DFT2G is a 1-bit configurable dual-supply voltage level translator produced by onsemi. This device is designed to translate voltage levels between two different power supply rails, VCCA and VCCB, which can operate within a wide range of 0.9 V to 4.5 V. This flexibility makes it suitable for various low-voltage translation applications. The NLSV1T34DFT2G features high-speed operation with balanced propagation delay and includes overvoltage tolerance (OVT) protection up to 4.5 V on both inputs and outputs. It is available in several ultra-small packaging options, including SC-88A (SOT-353/SC-70), UDFN6, and ULLGA6, making it ideal for space-constrained designs.
