Dual-supply voltage level translator/transceiver; 3-state
Rev. 4 — 3 August 2012
Product data sheet
1. General description
The 74AVCH1T45 is a single bit, dual supply transceiver that enables bidirectional level
translation. It features two 1-bit input-output ports (A and B), a direction control input (DIR)
and dual supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can be supplied at any
voltage between 0.8 V and 3.6 V making the device suitable for translating between any of
the low voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins A and DIR are
referenced to VCC(A) and pin B is referenced to VCC(B). A HIGH on DIR allows
transmission from A to B and a LOW on DIR allows transmission from B to A.
The device is fully specified for partial power-down applications using IOFF. The IOFF
circuitry disables the output, preventing any damaging backflow current through the
device when it is powered down. In suspend mode when either VCC(A) or VCC(B) are at
GND level, both A and B are in the high-impedance OFF-state.
The 74AVCH1T45 has active bus hold circuitry which is provided to hold unused or
floating data inputs at a valid logic level. This feature eliminates the need for external
pull-up or pull-down resistors.

CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD  VCC2  fi  N + (CL  VCC2  fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
(CL  VCC2  fo) = sum of the outputs.

13.2 Bidirectional logic level-shifting application
Figure 10 shows the 74AVCH1T45 being used in a bidirectional logic level-shifting
application. Since the device does not have an output enable pin, the system designer
should take precautions to avoid bus contention between system-1 and system-2 when
changing directions.

13.3 Power-up considerations
The device is designed such that no special power-up sequence is required other than
GND being applied first.

13.4 Enable times
The enable times for the 74AVCH1T45 are calculate from the following formulas:
• ten (DIR to A) = tdis (DIR to B) + tpd (B to A)
• ten (DIR to B) = tdis (DIR to A) + tpd (A to B)
In a bidirectional application, these enable times provide the maximum delay from the
time the DIR bit is switched until an output is expected. For example, if the 74AVCH1T45
initially is transmitting from A to B, then the DIR bit is switched, the B port of the device
must be disabled before presenting it with an input. After the B port has been disabled, an
input signal applied to it appears on the corresponding A port after the specified
propagation delay.

Product data sheet
Suitability for use — NXP Semiconductors products are not designed,
authorized or warranted to be suitable for use in life support, life-critical or
safety-critical systems or equipment, nor in applications where failure or
malfunction of an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors and its suppliers accept no liability for
inclusion and/or use of NXP Semiconductors products in such equipment or
applications and therefore such inclusion and/or use is at the customer’s own
risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. NXP Semiconductors makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
NXP Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the
customer’s applications or products, or the application or use by customer’s
third party customer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using NXP
Semiconductors products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). NXP does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
Terms and conditions of commercial sale — NXP Semiconductors
products are sold subject to the general terms and conditions of commercial
sale, as published at http://www.nxp.com/profile/terms, unless otherwise
agreed in a valid written individual agreement. In case an individual
agreement is concluded only the terms and conditions of the respective
agreement shall apply. NXP Semiconductors hereby expressly objects to
applying the customer’s general terms and conditions with regard to the
purchase of NXP Semiconductors products by customer.
No offer to sell or license — Nothing in this document may be interpreted or
construed as an offer to sell products that is open for acceptance or the grant,
conveyance or implication of any license under any copyrights, patents or
other industrial or intellectual property rights.
