description/ordering information

This 16-bit noninverting bus transceiver uses two

separate configurable power-supply rails. The

SN74AVC16T245 is optimized to operate with

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

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 SN74AVC16T245 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.
