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 SN74AVC6T622 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 SN74AVC6T622 an ideal choice for these applications.
