Product details

Dual-supply bus switch for level translation

The Toshiba TC7QPB9307FK(EL) is a 4-channel 1:1 bus switch designed for isolating or connecting digital signal paths.

Supply rails and signal routing

The dual-supply architecture lets the switch pass digital signals between two voltage domains without an external level shifter. 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.

Frequently asked questions

Is TC7QPB9307FK(EL) a single or dual supply bus switch?

It is a dual-supply bus switch, with separate voltage rails for the control logic and the pass-gate section. This enables level translation between two independent voltage domains.

What package does TC7QPB9307FK(EL) come in?

It is supplied in a 14-VFSOP (3.00 mm width) package, also designated as 14-VSSOP. The package is surface-mount and suitable for compact PCB layouts.

Is TC7QPB9307FK(EL) RoHS compliant?

Yes, it is ROHS3 compliant, meeting the latest RoHS directive requirements for lead-free and restricted-substance-free manufacturing.
