DESCRIPTION:
FEATURES:
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-statecontrolprovideefficientaddressdistribution. Oneormorebanksmay
beusedforclockdistribution.
• 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)
• Reduced system switching noise
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
• VCC = 5V ± 10%
• Low input and output leakage ≤ 1µA (max.)
• Available in SSOP and TSSOP packages

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V). All other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ∆ICC DHNT + ICCD (fCPNCP/2 + fiNi)
ICC = Quiescent Current (ICCL, ICCH and ICCZ)
∆ICC = Power Supply Current for a TTL High Input (VIN = 3.4V)
DH = Duty Cycle for TTL Inputs High
NT = Number of TTL Inputs at DH
ICCD = Dynamic Current caused by an Input Transition Pair (HLH or LHL)
fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices)
NCP = Number of Clock Inputs at fCP
