FAST CMOS ADDRESS/ CLOCK DRIVER IDT54/74FCT162344AT/CT/ET Integrated Device Technology, Inc. FEATURES: 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. • • • • • • 0.5 MICRON CMOS Technology Ideal for address line driving and clock distribution 8 banks with 1:4 fanout and 3-state Typical tSK(o) (Output Skew) < 500ps Balanced Output Drivers: ±24mA (commercial), ±16mA (military) Reduced system switching noise ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) Packages include 25 mil pitch SSOP, 19.6 mil pitch TSSOP, 15.7 mil pitch TVSOP and 25 mil pitch Cerpack Extended commercial range of -40°C to +85°C VCC = 5V ±10% Low input and output leakage ≤ 1µA (max.)
