3 Description

This 16-bit noninverting bus transceiver uses

two separate configurable power-supply rails. The

SN74AVC16T245 device is optimized to operate

with VCCA/VCCB set at 1.4V to 3.6V. The device is

operational with VCCA/VCCB as low as 1.2V. The A port

is designed to track VCCA. VCCA accepts any supply

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

to track VCCB. VCCB accepts any supply voltage from

1.2V to 3.6V. This allows for universal low-voltage

bidirectional translation between any of the 1.2V, 1.5V,

1.8V, 2.5V, and 3.3V voltage nodes.

The SN74AVC16T245 device 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 effectively are isolated.

The SN74AVC16T245 control pins (1DIR, 2DIR, 1

OE, and 2 OE) are supplied by VCCA.
