Introducing TI’s TXS0206 Voltage-Level Translators

Arrow Electronics and Texas Instruments now offer complete standard linear and logic solutions ranging from op amps, LDO regulators, and peripheral drivers, to RS-232, RS-422, RS-485, I²C, voltage level translation, and more—all backed by the support of Arrow’s world-class services, solutions, and technical know-how.

The TXS0206 is a level shifter for interfacing microprocessors with MultiMediaCards (MMCs), secure digital (SD) cards, and Memory Stick™ cards. It includes a high-speed level translator along with ESD protection and EMI filtering circuitry.

The voltage-level translator has two supply voltage pins. VCCA as well as VCCB can be operated over the full range of 1.1 V to 3.6 V. The TXS0206 enables system designers to easily interface applications processors or digital basebands to memory cards and SDIO peripherals operating at a different I/O voltage level.

Memory card standards recommend high-ESD protection for devices that connect directly to the external memory card. To meet this need, the TXS0206 incorporates ±15-kV Air-Gap Discharge and ±8-kV Contact Discharge protection on the card side.

Features:

• Level Translator
  • VCCA and VCCB Range of 1.1 V to 3.6 V
  • Fast Propagation Delay (4 ns Max When Translating Between 1.8 V and 3 V)
• Integrated EMI Filtering and ESD Protection Circuitry
• ESD Protection Exceeds JESD 22 (A Port)
  • 2500-V Human-Body Model (A114-B)
  • 250-V Machine Model (A115-A)
  • 1500-V Charged-Device Model (C101)
• IEC 61000-4-2 ESD (B Port)
  • ±8-kV Contact Discharge
  • ±4-kV Air-Gap Discharge

Packaging Information:
The TXS0206 is offered in a 20-bump wafer chip scale package (WCSP). This package has dimensions of 1.96 mm × 1.56 mm, with a 0.4-mm ball pitch for effective board-space savings. Memory cards are widely used in mobile phones, PDAs, digital cameras, personal media players, camcorders, set-top boxes, etc. Low static power consumption and small package size make the TXS0206 an ideal choice for these applications.
