74ALVC244
Octal buffer/line driver; 3-state
Rev. 4 — 10 October 2017 Product data sheet
1 General description
The 74ALVC244 is a high-performance, low-power, low-voltage, Si-gate CMOS device
and superior to most advanced CMOS compatible TTL families.
The 74ALVC244 is an octal non-inverting buffer/line driver with 3-state outputs. The
3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE
causes the outputs to assume a high-impedance OFF-state. Schmitt-trigger action at all
inputs makes the circuit highly tolerant for slower input rise and fall times.
2 Features and benefits
•Wide supply voltage range from 1.65 V to 3.6 V
•3.6 V tolerant inputs/outputs
•CMOS low power consumption
•Direct interface with TTL levels (2.7 V to 3.6 V)
•Power-down mode
•Latch-up performance exceeds 250 mA
•Complies with JEDEC standards:
–JESD8-7 (1.65 V to 1.95 V)
–JESD8-5 (2.3 V to 2.7 V)
–JESD8B/JESD36 (2.7 V to 3.6 V)
•ESD protection:
–HBM JESD22-A114E exceeds 2000 V
–MM JESD22-A115-A exceeds 200 V

Suitability for use — Nexperia products are not designed, authorized or
warranted to be suitable for use in life support, life-critical or safety-critical

of an Nexperia product can reasonably be expected to result in personal
injury, death or severe property or environmental damage. Nexperia and its
suppliers accept no liability for inclusion and/or use of Nexperia 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. Nexperia 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 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 minimize the risks
associated with their applications and products. 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.
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.
