Industry´s smallest voltage level translator

Consumer electronics designers save cost and board space with the industry’s smallest, most highly integrated SD/MMC voltage level translator
Engineers can now bridge the gap between two disparate voltage nodes while maintaining digital switching compatibility by using a tiny, highly integrated Secure Digital (SD)/MultiMedia Card (MMC) level shifter, introduced by Texas Instruments (TI).
The translator’s auto-direction circuitry simplifies board design by eliminating the need for customers to program a General Purpose Input/Output (GPIO) on a processor for direction control and thereby reduces the number of required pins. Highly integrated features of the TXS0206, packaged in a 2 mm x 1.6 mm wafer chip-scale package (WCSP), eliminate the need for more than 10 external discrete components and reduce overall system cost in consumer electronics, such as mobile handsets, digital cameras and portable navigation devices.
