CAVC16T245QDGVRQ1

The SN74AVC16T245-Q1 is a 16-bit non-inverting bus transceiver with two independently configurable power rails. The SN74AVC16T245-Q1 is optimized for operation when VCCA or VCCB is set within the range of 1.4V to 3.6V, and also supports operation with VCCA or VCCB as low as 1.2V. Port A is designed to track VCCA, with a VCCA supply voltage range of 1.2V to 3.6V. Port B is designed to track VCCB, with a VCCB supply voltage range of 1.2V to 3.6V. This enables general-purpose low-voltage bidirectional translation between 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V voltage nodes. The SN74AVC16T245-Q1 is designed for asynchronous communication between data buses. Based on the logic level at the direction control (DIR) input, the device transmits data from the A bus to the B bus, or from the B bus to the A bus. The output enable (OE) input can be used to disable the outputs, effectively isolating the buses. The SN74AVC16T245-Q1 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are powered by VCCA. The device is fully suitable for partial power-down applications using Ioff. The Ioff circuit disables the outputs to prevent damaging backflow current during the device's power-down mode. The VCC isolation feature ensures that both ports are placed in a high-impedance state whenever any VCC input is tied to GND. To ensure the high-impedance state during power-up or power-down, OE must be connected to VCC through a pullup resistor; the minimum resistance value is determined by the current sinking capability of the driver.
