74LVT245
3.3 V octal transceiver with direction pin (3-state)
Rev. 4 — 24 December 2013
Product data sheet
1. General description
The 74LVT245 is a high-performance BiCMOS product designed for VCC operation at
3.3 V.
This device is an octal transceiver featuring non-inverting 3-state bus compatible outputs
in both send and receive directions. The control function implementation minimizes
external timing requirements. It features an output enable (OE) input for easy cascading
and a direction (DIR) input for direction control.
2. Features and benefits
3-state buffers
Octal bidirectional bus interface
Input and output interface capability to systems at 5 V supply
TTL input and output switching levels
Output capability: +64 mA/32 mA
Latch-up protection exceeds 500 mA per JESD78 class II level A
ESD protection:
HBM JESD22-A114E exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs
Live insertion/extraction permitted
Power-up 3-state
No bus current loading when output is tied to 5 V bus

Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
[2]
The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 C.
[3]
The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
[4]
For SO20 packages: above 70 C derate linearly with 8 mW/K.
For SSOP20 and TSSOP20 packages: above 60 C derate linearly with 5.5 mW/K.
For DHVQFN20 packages: above 60 C derate linearly with 4.5 mW/K.

This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 3.3 V 0.3 V
a transition time of 100 ms is permitted. This parameter is valid for Tamb = +25 C only.

This is the bus hold overdrive current required to force the input to the opposite logic state.

Product data sheet
Suitability for use — Nexperia products are not designed,
authorized or warranted to be suitable for use in life support, life-critical or
safety-critical systems or equipment, nor in applications where failure or
malfunction of a 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.
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
