FXLA104UM12X from ON Semiconductor is a logic translator and level shifter intended for designs that need reliable signal interfacing between devices operating at different logic domains. Parts in this category are commonly considered for embedded systems, portable electronics, communication modules, industrial control boards, and mixed-voltage digital subsystems where clean interoperability is important. Engineers typically evaluate devices like this when connecting processors, sensors, memory, peripherals, or FPGA-related logic across voltage boundaries without redesigning the full signal chain. As an ON Semiconductor offering, FXLA104UM12X is positioned for practical digital interface translation use in compact, performance-sensitive applications. The current lifecycle status is information not available, so design teams should confirm whether the device is active, NRND, or approaching end-of-life through official manufacturer channels before locking it into new programs. RoHS compliance information is also not available in the provided data and should be verified using the latest datasheet, compliance certificate, or manufacturer declaration before procurement.
