DESCRIPTION: The FCT162344AT/CT/ET is a 1:4 address line driver built using advanced dual metal CMOS technology. This highspeed, low power device provides the ability to fanout to memory arrays. Eight banks, each with a fanout of 4, and 3state 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.
