DESCRIPTION

The 74ALVT162344 high-performance BiCMOS device combines

low static and dynamic power dissipation with high speed and high

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 30

Ω 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.
