description/ordering information
This 16-bit (dual-octal) noninverting bus
transceiver contains two separate supply rails.
B port has V
CCB
, which is set to operate at 3.3 V
and 5 V. A port has V
CCA
, which is set to operate
at 2.5 V and 3.3 V. This allows for translation from
a 2.5-V to a 3.3-V environment, and vice versa, or
from a 3.3-V to a 5-V environment, and vice versa.
The SN74ALVC164245 is designed for
asynchronous communication between data
buses.
To ensure the high-impedance state during power
up or power down, the output-enable (OE) input
should be tied to V
CC
through a pullup resistor; the
minimum value of the resistor is determined by the
current-sinking capability of the driver.
