DESCRIPTION/ORDERING INFORMATION
The SN74AVCA406E is a transceiver for interfacing microprocessors with MultiMediaCards (MMCs) and secure
digital (SD) cards.

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 k
Pullup Resistors
That are Realized Via the WP and CD Pins
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 V
CCA
, while the B port is designed to track V
CCB
. V
CCA
and V
CCB
can accept any
supply voltage from 1.2 V to 3.6 V.
If either V
CC
is switched off (V
CCA
= 0 V and/or V
CCB
= 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.
