SN74AXC8T245-Q1 Automotive 8-Bit Dual-Supply Bus Transceiver With Configurable
Voltage Translation and Tri-State Outputs
The SN74AXC8T245-Q1 device is designed for
asynchronous communication between data buses.
1 Features
•
•
AEC-Q100 qualified for automotive applications
Qualified fully configurable dual-rail design allows
each port to operate with a power supply range
from 0.65 V to 3.6 V
Operating temperature from –40°C to +125°C
Multiple direction-control pins to allow
simultaneous up and down translation
Up to 380 Mbps support when translating from 1.8
V to 3.3 V
VCC isolation feature to effectively Isolate both
bses in a power-down scenario
Partial power-down mode to limit backflow current
in a power-down scenario
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 (DIR1 and DIR2).
The output-enable (OE) input is used to disable the
outputs so the buses are effectively isolated.
•
•
The SN74AXC8T245-Q1 device is designed so the
control pins (DIR and OE) are referenced to VCCA
.
•
•
•
This device is fully specified for partial-power-down
applications using Ioff. The Ioff circuitry disables
the outputs when the device is powered down.
This inhibits current backflow into the device which
prevents damage to the device.
•
•
Compatible with SN74AVC8T245-Q1 level shifter
Latch-up performance exceeds 100 mA per JESD
78, class II
The VCC isolation feature ensures that if either VCC
input supply is below 100 mV, all level shifter outputs
are disabled and placed into a high-impedance state.
2 Applications
To ensure the high-impedance state of the level shifter
I/Os during power up or power down, OE should be
tied to VCCA through a pullup resistor; the minimum
value of the resistor is determined by the current-
sinking capability of the driver.

3.50 mm × 5.50 mm
The SN74AXC8T245-Q1 AEC-Q100 qualified device
is an 8-bit non-inverting bus transceiver that resolves
voltage level mismatch between devices operating at
the latest voltage nodes (0.7 V, 0.8 V, and 0.9 V) and
devices operating at industry standard voltage nodes
(1.8 V, 2.5 V, and 3.3 V) and vice versa.

(1) For all available packages, see the orderable addendum at
the end of the data sheet.
The device operates by using two independent power-
supply rails (VCCA and VCCB) that operate as low as
0.65 V. Data pins A1 through A8 are designed to track
VCCA, which accepts any supply voltage from 0.65 V
to 3.6 V. Data pins B1 through B8 are designed to
track VCCB, which accepts any supply voltage from
0.65 V to 3.6 V.

8 Detailed Description
8.1 Overview
The SN74AXC8T245-Q1 device is an 8-bit, dual-supply non-inverting transceiver with bidirectional voltage level
translation. The I/O pins labeled with A and the control pins (DIR1, DIR2, and OE) are supported by VCCA, and
the I/O pins labeled with B are supported by VCCB. The A port and the B port are able to accept I/O voltages
ranging from 0.65 V to 3.6 V.

8.3 Feature Description
8.3.1 Up-Translation and Down-Translation From 0.65 V to 3.6 V
Both supply pins are configured from 0.65 V to 3.6 V, which makes the device suitable for translating between
any of the low voltage nodes (0.7 V, 0.8 V, 0.9 V, 1.2 V, 1.8 V, 2.5 V, and 3.3 V).
8.3.2 Multiple Direction Control Pins
Two control pins are used to configure the 8 data I/Os. I/O channels 1 through 4 are grouped together and
I/O channels 5 through 8 are banked together. The benefit of this is to permit simultaneous up-translation and
down-translation within one device. This eliminates the need for multiple devices, where each device can only
provide up-translation or down-translation sequentially. Simultaneous up and down translation is supported when
both VCCA and VCCB are at least 1.40 V.
8.3.3 Ioff Supports Partial-Power-Down Mode Operation
This feature is to limit the leakage current of an I/O pin being driven to a voltage as large as 3.6 V while having
its corresponding power supply rail powered down. This is represented by the Ioff parameter in the Electrical
Characteristics table.
8.4 Device Functional Modes
All control inputs are referenced to VCCA and must be driven to a valid Logic High or Logic Low (that is, not
floating) to assure proper device operation and to prevent excessive power consumption. Table 8-1 summarizes
the possible modes of device operation based on the configuration of the control inputs.

9 Application and Implementation
Note
Information in the following applications sections is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI’s customers are responsible for
determining suitability of components for their purposes, as well as validating and testing their design
implementation to confirm system functionality.
9.1 Application Information
The AEC-Q100 qualified SN74AXC8T245-Q1 device can be used in level-translation applications for interfacing
devices or systems operating at different voltage nodes. Figure 9-1 depicts an application in which the
SN74AXC8T245-Q1 device is up-translating a 0.7 V input to a 3.3 V output to interface between a system
controller and a peripheral device.

EXAMPLE VALUE
Input voltage range
0.65 V to 3.6 V
0.65 V to 3.6 V
Output voltage range
9.2.2 Detailed Design Procedure
To begin the design process, determine the following:
•
Input voltage range
– Use the supply voltage of the device that is driving the SN74AXC8T245-Q1 device to determine the input
voltage range. For a valid logic high the value must exceed the VIH of the input port. For a valid logic low
the value must be less than the VIL of the input port.
•
Output voltage range
– Use the supply voltage of the device that the SN74AXC8T245-Q1 device is driving to determine the output
voltage range.

10 Power Supply Recommendations
Always apply a ground reference to the GND pins first. There are no additional requirements for power supply
sequencing.
This device was designed with various power supply sequencing methods in mind to help prevent unintended
triggering of downstream devices. For more information regarding the power up glitch performance of the AXC
family of level translators, see the Power Sequencing for AXC Family of Devices application report.
11 Layout
11.1 Layout Guidelines
To assure reliability of the device, follow common printed-circuit board layout guidelines.
•
•
•
Use bypass capacitors on power supplies.
Use short trace lengths to avoid excessive loading.
Place pads on the signal paths for loading capacitors or pullup resistors to help adjust rise and fall times of
signals depending on the system requirements.
