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 5.5 V, and the A port is designed to
track V
CCA
, which operates at 2.3 V to 3.6 V. This
allows for translation from a 3.3-V to a 5-V system
environment and vice versa, or from a 2.5-V to a
3.3-V system environment and vice versa.
The SN74LVCC3245A 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 SN74LVCC3245A is characterized for operation from –40
°
C to 85
°
C.
