1 / 20 page 1 FEATURES DESCRIPTION/ORDERING INFORMATION SN74AVCA406E MMC AND SD CARD VOLTAGE-TRANSLATION TRANSCEIVER SCES659C – OCTOBER 2007 – REVISED MARCH 2008 www.ti.com 2 • Transceiver for Memory Card Interface • ESD Protection [MultiMediaCard (MMC) and Secure Digital – ±8-kV Contact Discharge (SD) Compliant Products] – ±15-kV Air-Gap Discharge • Configurable I/O Switching Levels With • EMI Filtering Dual-Supply Pins Operating Over Full 1.2-V to • Integrated Pullup and Pulldown Resistors on 3.6-V Power-Supply Range Card-Side I/Os per SD Specification • Latch-Up Performance Exceeds 100 mA Per • ZQS Package Has 100-kΩ Pullup Resistors Via JESD 78, Class II WP and CD Pins 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.
