This arrangement is common in mixed-voltage designs where an MCU at 1.8 V needs to drive a 3.3 V peripheral bus. With four independent 1:1 channels in a single 14-VSSOP package, the part saves board area compared to discrete FET switches. The 14-VFSOP footprint (3.00 mm width) is compact enough for space-constrained PCBs in handheld or embedded modules.","metaTitle":"TC7QPB9307FK(EL) Bus Switch, 4 x 1:1, Dual Supply 1.65V–5.5V","metaDescription":"TC7QPB9307FK(EL) bus switch from Toshiba, 4 x 1:1 circuit, dual supply 1.65V–5.5V, -40°C to 85°C, 14-VSSOP.
