SN74AVC16T245 16-Bit Dual-Supply Bus Transceiver

with Congurable Level-Shifting / Voltage Translation and Tri-State Outputs

• VCC Isolation Feature – If Either VCC Input Is at VCCA/VCCB set at 1.4 V to 3.6 V. The device is

GND, Both Ports Are in the High-Impedance State operational with VCCA/VCCB as low as 1.2 V. The A

port is designed to track VCCA. VCCA accepts any

• Overvoltage-Tolerant Inputs and Outputs Allow

supply voltage from 1.2 V to 3.6 V. The B port is

Mixed-Voltage-Mode Data Communications designed to track VCCB. VCCB accepts any supply

• Fully Congurable Dual-Rail Design Allows Each voltage from 1.2 V to 3.6 V. This allows for universal

Port to Operate Over the Full 1.2 V to 3.6 V low-voltage bidirectional translation between any of

Power-Supply Range the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage

• Io Supports Partial-Power-Down Mode Operation nodes.

• I/Os Are 4.6 V Tolerant The SN74AVC16T245 device is designed for

• Maximum Data Rates asynchronous communication between data buses.

The device transmits data from the A bus to the B

– 380 Mbps (1.8 V to 3.3 V Level-Shifting) bus or from the B bus to the A bus, depending on the

– 200 Mbps (<1.8 V to 3.3 V Level-Shifting) logic level at the direction-control (DIR) input. The

– 200 Mbps (Level-Shifting to 2.5 V or 1.8 V) output-enable (OE) input can be used to disable the

outputs so the buses eectively are isolated.

– 150 Mbps (Level-Shifting to 1.5 V)

– 100 Mbps (Level-Shifting to 1.2 V) The SN74AVC16T245 control pins (1DIR, 2DIR,

1OE, and 2OE) are supplied by VCCA.

5 Description (continued)

This device is fully specied for partial-power-down applications using Io. The Io circuitry disables the outputs,

preventing damaging current backow 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 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.
