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. The control
circuitry (1DIR, 2DIR, 1OE, and 2OE) is powered by
V_CCA.
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.
