and 200 V per Machine Model
DESCRIPTION
The 74ALVT162344 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 74ALVT162344 is a 1-to-4 address driver used in applications
where four separate memory locations must be addressed by a
single address.
The 74ALVT162344 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.
•
Outputs include series resistance of 30Ω making external
termination resistors unnecessary

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 negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
