SN74AVCA406 Overview
/ORDERING INFORMATION The SN74AVCA406 is a transceiver for interfacing microprocessors with MultiMediaCards (MMCs), secure digital (SD) cards, Memory Stick™ pliant 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 switching thresholds to be configured separately.
