74AHCV245A
Octal bus transceiver; 3-state
Rev. 1 — 10 June 2016
Product data sheet
1. General description
The 74AHCV245A is an 8-bit transceiver with 3-state outputs and Schmitt trigger inputs.
The device features an output enable (OE) and send/receive (DIR) for direction control. A
HIGH on OE causes the outputs to assume a high-impedance OFF-state.
Inputs are overvoltage tolerant. This feature allows the use of these devices as translators
in mixed voltage environments.
The data (An, Bn) and control (OE and DIR) inputs include Schmitt trigger inputs. These
inputs can of transform slowly changing input signals into sharply defined, jitter-free output
signals.
This device is ideal for driving bus lines or buffer memory address registers. It features
inputs and outputs on opposite sides of the package to facilitate printed circuit board
layout.
This device is fully specified for partial Power-down applications using IOFF.
The IOFF circuitry disables the output, preventing the damaging backflow current through
the device when it is powered down.
2. Features and benefits
Wide supply voltage range from 1.8 V to 5.5 V
Typical tpd of 3.2 ns at 5 V
Typical VOL(p) < 0.8 V at VCC = 3.3 V, Tamb = 25 C

Supports mixed-mode voltage operation on all ports
IOFF circuitry provides partial Power-down mode operation
Latch-up performance exceeds 250 mA per JESD 78 Class II
ESD protection:
HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 3 kV

(1) This pad 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.

Product data sheet
Suitability for use — NXP Semiconductors 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 an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors and its suppliers accept 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.
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.
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.
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.
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 — 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
