The SN74AVC16T245-Q1 is a 16-bit noninverting bus transceiver that uses two separate configurable power-supply rails. The SN74AVC16T245-Q1 is optimized to operate with VCCA or VCCB set at 1.4 V to 3.6 V. It is operational with VCCA or VCCB as low as 1.2 V. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.
●The SN74AVC16T245-Q1 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 outputs so the buses effectively are isolated.
●The SN74AVC16T245-Q1 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by VCCA.
●This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
●The VCC isolation feature ensures that if either VCC input is at GND, both ports are in the high-impedance state.
●To ensure the high-impedance state during power up or power down, OE must be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
