3 Description
This 16-bit noninverting bus transceiver uses two
separate configurable power-supply rails. The
SN74AVC16T245 device is optimized to operate with
V_CCA/V_CCB set at 1.4 V to 3.6 V. The device is
operational with V_CCA/V_CCB as low as 1.2 V. The A
port is designed to track V_CCA. V_CCA accepts any
supply voltage from 1.2 V to 3.6 V. The B port is
designed to track V_CCB. V_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 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,
1OE, and 2OE) are supplied by V_CCA.
