from 3 V to 5.5 V, and the A port is designed to track V
, which operates at 2.3 V to 3.6 V . This
CCA
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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. This value is limited to 6 V maximum.
2. This value is limited to 4.6 V maximum.
