•Fully Congurable Dual-Rail Design Allows Eachvoltage from1.2 Vto 3.6V. Thisallows foruniversal

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

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

The device transmits data from the A bus to the B

–380 Mbps (1.8 V to 3.3 V Level-Shifting)bus orfrom theB busto the Abus, dependingon the

–200 Mbps (<1.8 V to 3.3 V Level-Shifting)logic levelat thedirection-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ectivelyare 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.
