SN74AVCA406 ESD-PROTECTED VOLTAGE-TRANSLATION TRANSCEIVER

ORDERING INFORMATION The SN74AVCA406 is a transceiver for interfacing microprocessors with MultiMediaCards (MMCs), secure digital (SD) cards, Memory Stick™ compliant products, SmartMedia cards, or xD-Picture Cards™. It integrates high ESD protection, which eliminates the need for external ESD diodes. Two supply-voltage pins allow the A-port and B-port input .

Features

• Transceiver for Memory Card Interface [MultiMediaCard (MMC), Secure Digital (SD), Memory Stick™ Compliant Products, SmartMedia Card, and xD-Picture Card™]
• Configurable I/O Switching Levels With Dual-Supply Pins Operating Over Full 1.4-V to 3.6-V Power-Supply Range
• For Low-Power Operation, A Ports Are Placed in High-Impedance State When Card-Side Supply Voltage Is Switched Off
• Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
• ESD Protection for Card-Side Pins (B Port)
