DESCRIPTION/ORDERING INFORMATION
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, 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 control circuitry (DIR, OE) is powered by V_CCA.
