Description

The SN74AVCA406L is a transceiver for interfacing microprocessors with MultiMediaCards (MMCs), secure digital (SD) cards, and Memory Stick™ compliant products.

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 SN74AVCA406L enables system designers to easily interface low-voltage microprocessors to different memory cards operating at higher voltages.

The SN74AVCA406L 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 SN74AVCA406L an ideal choice for these applications.
