74AVCH2T45
Dual-bit, dual-supply voltage level translator/transceiver;
3-state
Rev. 8 — 7 December 2022
Product data sheet
1. General description
The 74AVCH2T45 is a dual bit, dual supply transceiver that enables bidirectional level translation.
It features two data input-output ports (nA and nB), 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 nA and DIR are referenced to VCC(A) and pins nB are
referenced to VCC(B). A HIGH on DIR allows transmission from nA to nB and a LOW on DIR allows
transmission from nB to nA.
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 74AVCH2T45 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.

IBHH should be measured after raising VI to VCC and then lowering it to VIH min.
[5] An external driver must source at least IBHLO to switch this node from LOW to HIGH.
[6] An external driver must sink at least IBHHO to switch this node from HIGH to LOW.
[7] For I/O ports, the parameter IOZ includes the input leakage current.

[1] CPD is used to determine the dynamic power dissipation (PD in μW).
PD = CPD × VCC 2 × fi × N + Σ(CL × VCC 2 × 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;
Σ(CL × VCC 2 × fo) = sum of the outputs.
[2] fi = 10 MHz; VI = GND to VCC; tr = tf = 1 ns; CL = 0 pF; RL = ∞ Ω.

12.2. Bidirectional logic level-shifting application
Fig. 7 shows the 74AVCH2T45 being used in a bidirectional logic level-shifting application. Since
the device does not have an output enable (OE) pin, the system designer should take precautions
to avoid bus contention between system-1 and system-2 when changing directions.

12.4. Enable times
The enable times for the 74AVCH2T45 are calculated from the following formulas:
•
•
ten (DIR to nA) = tdis (DIR to nB) + tpd (nB to nA)
ten (DIR to nB) = tdis (DIR to nA) + tpd (nA to nB)
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 74AVCH2T45 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.

Definitions
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.
Draft — The document is a draft version only. The content is still under
internal review and subject to formal approval, which may result in
modifications or additions. Nexperia does not give any representations or
warranties as to the accuracy or completeness of information included herein
and shall have no liability for the consequences of use of such information.
Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is
intended for quick reference only and should not be relied upon to contain
detailed and full information. For detailed and full information see the relevant
full data sheet, which is available on request via the local Nexperia sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.
Terms and conditions of commercial sale — Nexperia products are
sold subject to the general terms and conditions of commercial sale, as
published at http://www.nexperia.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. Nexperia hereby expressly objects to applying the customer’s general
terms and conditions with regard to the purchase of Nexperia products by
customer.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
Nexperia and its customer, unless Nexperia and customer have explicitly
agreed otherwise in writing. In no event however, shall an agreement be
valid in which the Nexperia product is deemed to offer functions and qualities
beyond those described in the Product data sheet.
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.

Non-automotive qualified products — Unless this data sheet expressly
states that this specific Nexperia product is automotive qualified, the
product is not suitable for automotive use. It is neither qualified nor tested in
accordance with automotive testing or application requirements. Nexperia
accepts no liability for inclusion and/or use of non-automotive qualified
products in automotive equipment or applications.
In no event shall Nexperia be liable for any indirect, incidental, punitive,
special or consequential damages (including - without limitation - lost

contract or any other legal theory.
In the event that customer uses the product for design-in and use in
automotive applications to automotive specifications and standards,
customer (a) shall use the product without Nexperia’s warranty of the
product for such automotive applications, use and specifications, and (b)
whenever customer uses the product for automotive applications beyond
Nexperia’s specifications such use shall be solely at customer’s own risk,
and (c) customer fully indemnifies Nexperia for any liability, damages or failed
product claims resulting from customer design and use of the product for
automotive applications beyond Nexperia’s standard warranty and Nexperia’s
product specifications.
Notwithstanding any damages that customer might incur for any reason
whatsoever, Nexperia’s aggregate and cumulative liability towards customer
for the products described herein shall be limited in accordance with the
