BU4S66G2-TR Description

Short technical summary and product information.

The BU4S66G2-TR is a single-pole single-throw normally open (SPST-NO) analog switch designed for general-purpose signal routing. It is manufactured by ROHM Semiconductor and offers a low on-resistance of 280Ω typical. The switch operates over a wide supply voltage range of 3V to 18V, making it suitable for battery-powered and industrial applications. With a low quiescent current of 300nA, it is ideal for power-sensitive designs.

 

The device features a 1:1 multiplexer configuration, effectively acting as a single switch. It has a channel off capacitance of 10pF, which helps maintain signal integrity in high-frequency applications. The operating temperature range of -40°C to 85°C allows use in harsh environments.

 

The BU4S66G2-TR is housed in a compact SC-74A (SOT-753) surface-mount package, with the supplier device package designated as 5-SSOP. This small footprint enables space-constrained designs. The switch is RoHS3 compliant and REACH unaffected, though these compliance statuses are unverified.
