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 SN74AVCH16T245 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 SN74AVCH16T245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by V
CCA
