The FCT162344T 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 FCT162344T 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.
