DESCRIPTION/ORDERING INFORMATION

This 24-bit noninverting bus transceiver uses two separate configurable power-supply rails. The

SN74AVC24T245 is optimized to operate with V_CCA/V_CCBset at 1.4 V to 3.6 V. It is operational with V_CCA/V_CCBas

low as 1.2 V. The A port is designed to track V_CCA. V_CCAaccepts any supply voltage from 1.2 V to 3.6 V. The

B port is designed to track V_CCB. V_CCBaccepts 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, 1OE, 2OE,

3OE, 4OE, 5OE, and 6OE) are supplied by V_CCA

This device is fully specified for partial-power-down applications using I_off. The I_offcircuitry disables the outputs,

preventing damaging current backflow through the device when it is powered down.

The V_CCisolation feature ensures that if either V_CCinput 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_CCAthrough a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
