Important notice
Dear Customer,
On 7 February 2017 the former NXP Standard Product business became a new company with the
tradename
Nexperia.
Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets
In data sheets and application notes which still contain NXP or Philips Semiconductors references, use
the references to Nexperia, as shown below.
Instead of http://www.nxp.com, http://www.philips.com/ or http://www.semiconductors.philips.com/,
use

Power-up 3-State
DESCRIPTION
The 74ALVT162827 high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed and high
output drive. It is designed for V
CC
operation at 2.5V or 3.3V with I/O
compatibility to 5V.
The 74ALVT162827 20-bit buffers provide high performance bus
interface buffering for wide data/address paths or buses carrying
parity. They have NOR Output Enables (nOE1, nOE2) for maximum
control flexibility.
The 74ALVT162827 is designed with 30Ω series resistance in both
the pull-up and pull-down output structures. This design reduces line
noise in applications such as memory address drivers, clock drivers
and bus receivers/transmitters.
•
Bus hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs

NOTES:
1. 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 voltage ratings may be exceeded if the input and output current ratings are observed.
