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.
