Bilateral switch

Rev. 13 — 9 September 2022

Product data sheet

1. General description

The 74LVC2G66 is a dual single pole, single-throw analog switch. Each switch has two input/output

terminals (nY and nZ) and a digital enable input (nE). When nE is LOW, the analog switch is turned

off. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these

devices as translators in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

2. Features and benefits

[1] To avoid sinking GND current from terminal nZ when switch current flows in terminal nY, the voltage drop across the bidirectional

switch must not exceed 0.4 V. If the switch current flows into terminal nZ, no GND current will flow from terminal nY. In this case, there

is no limit for the voltage drop across the switch.

[2] For overvoltage tolerant switch voltage capability, refer to 74LVCV2G66.

[3] Applies to control signal levels.

product development.

Customers are responsible for the design and operation of their applications

and products using Nexperia products, and Nexperia accepts no liability for

any assistance with applications or customer product design. It is customer’s

sole responsibility to determine whether the Nexperia 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

completing a design.

Nexperia 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 Nexperia 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). Nexperia does not accept any

liability in this respect.

[2] The term 'short data sheet' is explained in section "Definitions".

[3] The product status of device(s) described in this document may have

changed since this document was published and may differ in case of

multiple devices. The latest product status information is available on

the internet at https://www.nexperia.com.

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.

Export control — This document as well as the item(s) described herein

may be subject to export control regulations. Export might require a prior

authorization from competent authorities.

Disclaimers

Limited warranty and liability — Information in this document is believed

to be accurate and reliable. However, Nexperia does not give any

representations or warranties, expressed or implied, as to the accuracy

or completeness of such information and shall have no liability for the

consequences of use of such information. Nexperia takes no responsibility

for the content in this document if provided by an information source outside

of Nexperia.

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

profits, lost savings, business interruption, costs related to the removal

or replacement of any products or rework charges) whether or not such

damages are based on tort (including negligence), warranty, breach of

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)
