DESCRIPTION:
• Common features:
The FCT16240T/AT/CT/ET and FCT162240T/AT/CT/ET
– 0.5 MICRON CMOS Technology
16-bit buffer/line drivers are built using advanced dual metal
– High-speed, low-power CMOS replacement for
CMOS technology. These high-speed, low-power devices
ABT functions
offer bus/backplane interface capability with improved packing
Typical tSK(o) (Output Skew) < 250ps
– Low input and output leakage 1µA (max.)
density. The flow-through organization of signal pins simplifies
layout. The three-state controls are designed to operate these

– Power off disable outputs permit “live insertion”
The FCT162240T/AT/CT/ET have balanced output drive
– Typical VOLP (Output Ground Bounce) < 1.0V at
VCC = 5V, TA = 25°C
with current limiting resistors. This offers low ground bounce,
minimal undershoot, and controlled output fall times– reduc-

NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
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
fi = Input Frequency
Ni = Number of Inputs at fi
