description
This 8-bit (octal) noninverting bus transceiver
contains two separate supply rails. The B port is
designed to track V_CCB, which accepts voltages
from 3 V to 5 V, and the A port is designed to track
V_CCA, which is set to operate at 3.3 V. This allows
for translation from a 3.3-V to a 5-V environment
and vice versa.

The SN74LVCC3245 is designed for asynchronous communication between data buses. The device transmits
data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the
direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are
effectively isolated.
The SN74LVCC3245 is characterized for operation from –40°C to 85°C.
