Dual SPST USB switch with low on-resistance
The TC7WBL3305CFK,LF is a dual single-pole single-throw (SPST) analog switch from Toshiba's 7WBL series, designed for USB 2.0 signal switching and general-purpose analog or digital signal routing. Each of the two independent switches presents a maximum 19 Ohm on-resistance, keeping signal attenuation low in a 50-Ohm or 90-Ohm differential trace.
Supply voltage and logic-level compatibility
Operating from a single supply rail between 1.65 V and 3.6 V, the switch accepts control logic thresholds that track the supply.
Package footprint and board integration
Housed in an 8-VFSOP package (0.091" body width, 2.30 mm nominal), the part occupies a compact footprint roughly 2.3 mm x 2.0 mm. Surface-mount assembly with standard reflow profiles; no exposed thermal pad to manage.
Temperature grade and deployment environment
The 85°C ceiling means the part can sit next to a warm processor or power management IC without derating the on-resistance or leakage current.
RoHS compliant per the manufacturer's declaration. Sourced to order against BOM quantities; availability and current pricing confirmed at RFQ time.
