DESCRIPTION:
The FCT163344/A/C is a 1:4 address/clock driver built using advanced
dual metal CMOS technology. This high-speed, low power device provides
the ability to fanout to memory arrays. Eight banks, each with a fanout of
4, and 3-state control provide efficient address distribution. One or more
banks may be used for clock distribution.
The FCT163344/A/C have series current limiting resistors. These offer
low ground bounce, minimal undershoot and controlled output fall times,
reducing the need for external series terminating resistors.
A large number of power and ground pins ensure reduced noise levels.
All inputs are designed with hysteresis for improved noise margins.
The inputs of the FCT163344/A/C can be driven from either 3.3V or 5V
device. This feature allows the use of these devices as translators in a mixed
3.3V/5V supply system.
