IDT74ALVCH16345
DESCRIPTION:
This registered address line driver is built using advanced dual metal
CMOS technology. The ALVCH16345 is configured with banks of four
drivers, each to be used in high speed synchronous memory applica-
tions.
The ALVCH16345 is ideal for driving memory modules in systems
where multiple memory modules are used. One each of the four output
banks drives a different module; modules can be added or removed
without affecting the signal integrity of the other modules in the system.
Dual clock enables (CEx) allow use of the device in high speed memory
interleaving applications where the clock can be alternately enabled and
disabled, allowing the address to be held for additional cycles during
memory access.
The ALVCH16345 has been designed with a ±24mA output driver.
This driver is capable of driving a moderate to heavy load while
maintaining speed performance.
The ALVCH16345 has “bus-hold” which retains the inputs’ last state
whenever the input goes to a high impedance. This prevents floating
inputs and eliminates the need for pull-up/down resistors.
APPLICATIONS:
3.3V High Speed Systems
3.3V and lower voltage computing systems
High Speed Synchronous DRAM Modules
PC Motherboards
