This 24-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74AVC24T245 is optimized to operate with V_CCA/V_CCB set at 1.4 V to 3.6 V. It is operational with V_CCA/V_CCB as low as 1.2 V. The A port is designed to track V_CCA. V_CCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track V_CCB. V_CCB 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 SN74AVC24T245 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 are effectively isolated.

The SN74AVC24T245 is designed so that the control pins (1DIR, 2DIR, 3DIR, 4DIR, 5DIR, 6DIR, 1 OE, 2 OE, 3 OE, 4 OE, 5 OE, and 6 OE) are supplied by V_CCA.

This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

The V_CC isolation feature ensures that if either V_CC input is at GND, then both ports are in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE should be tied to V_CCA through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
