DRIVER
DESCRIPTION:
The FCT162344AT/CT/ET 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 FCT162344AT/CT/ET has balanced output drive with current
limiting resistors. This offers 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 and TTL output swings also
ensure reduced noise levels. All inputs are designed with hysteresis for
improved noise margins.
