BU4052BCFV-E2

The BU4052BCFV-E2 is a dual SP4T (single-pole 4-throw) analog switch, also configurable as a 4:1 multiplexer/demultiplexer, manufactured by ROHM Semiconductor. Each of the two switches has a maximum on-state resistance of 160 Ohms, making it suitable for low-frequency signal routing applications. The device operates over a wide supply voltage range of 3V to 18V, with a typical quiescent current of only 300nA, enabling low-power designs. The channel capacitance is 10pF, contributing to moderate signal integrity. The BU4052BCFV-E2 is designed for surface mount assembly and is housed in a 16-LSSOP (0.173", 4.40mm width) package, with a supplier device package of 16-SSOP-B. It can operate over an ambient temperature range of -40°C to +85°C, making it suitable for industrial and consumer applications. The device is claimed to be RoHS3 compliant, MSL level 1, and REACH unaffected, though these compliance claims are unverified. The part is available from distributors in tape and reel packaging (E2 suffix). Typical applications include signal multiplexing, analog switching, and data acquisition systems.
