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 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.
