DESCRIPTION
The 74AVC8T245Q is an 8-bit, dual-supply bus transceiver with configurable voltage translation. The An and Bn are 8-bit data input-output ports. DIR is the direction control input and OE is the output enable input. VCCA and VCCB are dual supply pins. The supply voltage of VCCA and VCCB can range from 0.8V to 3.6V, making the device suitable for bidirectional translating among any of the 0.8V, 1.2V, 1.5V, 1.8V, 2.5V and 3.3V voltage nodes. The An, DIR and OE signals are referenced to VCCA and Bn signals are referenced to VCCB.
When DIR is set high, it allows transmission from An to Bn. When DIR is set low, it allows transmission from Bn to An. OE can be used to make the outputs disabled so that the buses are effectively isolated. In suspend mode, both An and Bn are in high-impedance state when either VCCA or VCCB input is at GND level.
This device is highly suitable for partial power-down applications by using power-off leakage current (IOFF) circuit. When the device is powered down, the outputs are disabled, and the current backflow can be prevented from passing through the device.
This device is AEC-Q100 qualified (Automotive Electronics Council Standard Q100 Grade 1) and the use of this device is suitable for automotive applications.
