74LVC2244A  
Octal buffer/line driver; 30 Ω series termination; 5 V tolerant  
input/output; 3-state  
Rev. 6 — 20 September 2021  
Product data sheet  
1. General description  
The 74LVC2244A is an 8-bit buffer/line driver with 3-state outputs. The device can be used as  
two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE),  
each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a  
high-impedance OFF-state. 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.  
This device is fully specified for partial power down applications using IOFF. The IOFF circuitry  
disables the output, preventing the potentially damaging backflow current through the device when  
it is powered down.  
2. Features and benefits  
Overvoltage tolerant inputs to 5.5 V  
Wide supply voltage range from 1.2 V to 3.6 V  
CMOS low-power consumption  
Direct interface with TTL levels  
Integrated 30 Ω termination resistors  
IOFF circuitry provides partial Power-down mode operation  
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

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

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".

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

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

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)  
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
