SN74AVCA406E MMC AND SD CARD VOLTAGE-TRANSLATION TRANSCEIVER www.ti.com SCES659C – OCTOBER 2007 – REVISED MARCH 2008 FEATURES 1 • Transceiver for Memory Card Interface [MultiMediaCard (MMC) and Secure Digital (SD) Compliant Products] • Configurable I/O Switching Levels With Dual-Supply Pins Operating Over Full 1.2-V to 3.6-V Power-Supply Range • Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II 2 • • • • ESD Protection – ±8-kV Contact Discharge – ±15-kV Air-Gap Discharge EMI Filtering Integrated Pullup and Pulldown Resistors on Card-Side I/Os per SD Specification ZQS Package Has 100-kΩ Pullup Resistors Via WP and CD Pins DESCRIPTION/ORDERING INFORMATION The SN74AVCA406E is a transceiver for interfacing microprocessors with MultiMediaCards (MMCs) and secure digital (SD) cards. Two supply-voltage pins allow the A-port and B-port input switching thresholds to be configured separately. The A port is designed to track VCCA, while the B port is designed to track VCCB. VCCA and VCCB can accept any supply voltage from 1.2 V to 3.6 V. If either VCC is switched off (VCCA = 0 V and/or VCCB = 0 V), all outputs are placed in the high-impedance state to conserve power. The SN74AVCA406E enables system designers to easily interface low-voltage microprocessors to different memory cards operating at higher voltages. Memory card standards recommend high ESD protection for devices that connect directly to the external memory card. To meet this need, the SN74AVCA406E incorporates ±15-kV Air-Gap Discharge and ±8-kV Contact Discharge protection on the card side. The SN74AVCA406E is available in two 0.5-mm-pitch ball grid array (BGA) packages. The 20-ball package has dimensions of 3 mm × 2.5 mm, and the 24-ball package measures 3 mm × 3 mm. 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 SN74AVCA406E an ideal choice for these applications.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
