74LVC126A  
Quad buffer/line driver with 5 V tolerant input/outputs; 3-state  
Rev. 7 — 9 December 2011  
Product data sheet  
1. General description  
The 74LVC126A consists of four non-inverting buffers/line drivers with 3-state outputs,  
which are controlled by the output enable input (nOE). A LOW at nOE causes the outputs  
to assume a high-impedance OFF-state.  
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be  
applied to the outputs.  
2. Features and benefits  
5 V tolerant inputs/outputs for interfacing with 5 V logic  
Wide supply voltage range from 1.2 V to 3.6 V  
CMOS low power consumption  
Direct interface with TTL levels  
Complies with JEDEC standard:  
JESD8-7A (1.65 V to 1.95 V)  
JESD8-5A (2.3 V to 2.7 V)  
JESD8-C/JESD36 (2.7 V to 3.6 V)  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115B exceeds 200 V  
CDM JESD22-C101E exceeds 1000 V  
Specified from 40 C to +85 C and 40 C to +125 C

(1) This is not a supply pin. The substrate is attached to this  
pad using conductive die attach material. There is no  
electrical or mechanical requirement to solder this pad.  
However, if it is soldered, the solder land should remain  
floating or be connected to GND.

information is available on the Internet at URL http://www.nxp.com.  
malfunction of an NXP Semiconductors product can reasonably be expected  
15.2 Definitions  
to result in personal injury, death or severe property or environmental  
damage. NXP Semiconductors accepts 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.  
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. NXP Semiconductors 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.  
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.  
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 NXP Semiconductors sales  
office. In case of any inconsistency or conflict with the short data sheet, the  
full data sheet shall prevail.  
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.  
Product specification — The information and data provided in a Product  
data sheet shall define the specification of the product as agreed between  
NXP Semiconductors and its customer, unless NXP Semiconductors and  
customer have explicitly agreed otherwise in writing. In no event however,  
shall an agreement be valid in which the NXP Semiconductors product is  
deemed to offer functions and qualities beyond those described in the  
Product data sheet.  
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.  
15.3 Disclaimers  
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.  
Limited warranty and liability — Information in this document is believed to  
be accurate and reliable. However, NXP Semiconductors 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.  
In no event shall NXP Semiconductors 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.  
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.  
Notwithstanding any damages that customer might incur for any reason  
whatsoever, NXP Semiconductors’ aggregate and cumulative liability towards  
customer for the products described herein shall be limited in accordance  
with the Terms and conditions of commercial sale of NXP Semiconductors.  
Right to make changes — NXP Semiconductors reserves the right to make  
changes to information published in this document, including without  
limitation specifications and product descriptions, at any time and without  
notice. This document supersedes and replaces all information supplied prior  
to the publication hereof.

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.  
Suitability for use — NXP Semiconductors products are not designed,
