3 Description
The SN74AXC4T245-Q1 AEC-Q100 qualified device
is a four-bit non-inverting bus transceiver that uses
two individually configurable power-supply rails. The
device is operational with both VCCA and VCCB
supplies as low as 0.65 V. The A port is designed
to track VCCA, which accepts any supply voltage from
0.65 V to 3.6 V. The B port is designed to track
VCCB, which also accepts any supply voltage from
0.65 V to 3.6 V. Additionally the SN74AXC4T245-Q1
is compatible with a single-supply system.
The SN74AXC4T245-Q1 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 of the direction-control inputs (1DIR and 2DIR).
The output-enable inputs (1 OE and 2 OE) are used
to disable the outputs so the buses are effectively
isolated. The SN74AXC4T245-Q1 device is designed
so the control pins (xDIR and x OE) are referenced to
VCCA.
To ensure the high-impedance state of the level shifter
I/Os during power up or power down, the x OE pins
should be tied to VCCA through a pull-up resistor.
This device is fully specified for partial-power-down
applications using the Ioff current. The Ioff protection
circuitry ensures that no excessive current is drawn
from or to an input, output, or combined I/O that
is biased to a specific voltage while the device is
powered down.
The VCC isolation feature ensures that if either VCCA
or VCCB is less than 100 mV, both I/O ports enter a
high-impedance state by disabling their outputs.
Glitch-Free power supply sequencing allows either
supply rail to be powered on or off in any order while
providing robust power sequencing performance.
