Toshiba Announces Series of Small, High-Speed, Bidirectional Level Shifters for Mobile Devices

IRVINE, Calif., Oct. 24, 2012 /PRNewswire/ -- Toshiba America Electronic Components, Inc., (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced a new family of high-speed, bidirectional level shifters that feature ultra-small packages, including UQFN12, WCSP16 and WCSP24C. The new level shifters employ an automatic direction control function, and reduce concerns over the order in which power supplies start up.

With mobile devices having multiple functions and more core ICs operating at lower voltages than ever, the number of cases in which voltage signal levels differ between ICs is on the rise. Designed with the ability to respond to two different power supplies, Toshiba's full series of dual-supply level shifters is optimal as an interface between different power supply systems. Small package sizes and a reduced number of DIR pins contribute to a reduction in mounting area, making them ideal for mobile phones, digital still cameras and digital video recorders.

Among the new additions to the series are the 4-bit TC7LX0104MU, the 6-bit TC7LX1106WBG, the 8-bit TC7LX1108WBG and the four-circuit multiplexer/demultiplexer TC7LX1204WBG.

The TC7LX0104MU, TC7LX1106WBG and TC7LX1108WBG are dual-supply level shifters that allow for voltage translation between VCCA and VCCB systems in a power supply range from 1.2V to 3.6V - without a direction control signal for input and output signals. These level shifters are easier to use than other products, as they do not have any restrictions regarding the combination of the two power supplies (VCCA/VCCB) to be used- or the order in which they are started.

The TC7LX1204WBG is a four-circuit multiplexer/demultiplexer that enables a 1.2V to 3.6V voltage interface. With this product, bidirectional voltage-level translation is possible - without direction control signals. The TC7LX1204WBG employs three power supply voltages of VCCA, VCCB, and VCCC, and allows for any combination of power supply voltages.
