FAST CMOS ADDRESS/
CLOCK DRIVER
The FCT162344AT/CT/ET is a 1:4 address line 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.
