Toshiba Launches a Low-Capacitance SPDT Bus Switch IC for Small-Sized Mobile Applications

TOKYO - Wednesday, October 16th 2013 [ME NewsWire]

(BUSINESS WIRE)-- Toshiba Corporation (TOKYO:6502) today announced the launch of a low-capacitance SPDT (Single Pole Double Throw) bus switch IC, “TC7SB3157DL6X”, for digital equipment that requires high speed data processing. Mass production is scheduled to start in November this year.

The increasing volumes of data that digital equipment handles require high speed bus switch ICs. The “TC7SB3157DL6X” lowers switch terminal capacitance to reduce dullness at the rising and falling edge of signals, enabling their use in high-speed two-way communication and data switching. The product adopts MP6B, a small general purpose back electrode type package, allowing for use in applications that require high-density mounting, such as mobile digital equipment.

Key Features of New Product


High speed transmission by reduction in switch terminal capacitance.


Switch terminal ON-capacitance: CI/O (Typ.): 15pF @VCC=5.0V


ON-resistance RON (Typ.)

4.0Ω @ VCC=4.5V, VIS=0V

6.0Ω @ VCC=4.5V, VIS=4.5V


Supports a wide range of operating supply voltages: VCC=1.65V to 5.5V


Enables bi-directional interface without the DIR pin.


Adopts a small size MP6B package (1.45mm x 1.0mm).

Applications Small mobile devices, including mobile phones, tablet PCs, portable audio players, digital still cameras, and digital video cameras.
