DESCRIPTION:
• Common features:
The 16-Bit Buffer/Line Driver is for bus interface or signal buffering
– 0.5 MICRON CMOS Technology
applications requiring high speed and low power dissipation. These
– High-speed, low-power CMOS replacement for
devices have a flow through pin organization, and shrink packaging
ABT functions
to simplify board layout. All inputs are designed with hysteresis for
Typical tSK(o) (Output Skew) < 250ps

– Low input and output leakage 1µA (max.)
4-bit, 8-bit or combined 16-bit operation. These parts are plug in
– ESD > 2000V per MIL-STD-883, Method 3015;
replacements for 54/74ABT16244 where higher speed, lower noise
> 200V using machine model (C = 200pF, R = 0)
or lower power dissipation levels are desired.
– Packages include 25 mil pitch SSOP, 19.6 mil pitch
The FCT16244T/AT/CT/ET are ideally suited for driving
TSSOP, 15.7 mil pitch TVSOP and 25 mil pitch Cerpack high capacitance loads (>200pF) and low impedance
– Extended commercial range of -40°C to +85°C
backplanes. These "high drive" buffers are designed with
• Features for FCT16244T/AT/CT/ET:
power off disable capability to allow "live insertion" of boards
– High drive outputs (-32mA IOH, 64mA IOL)
when used in a backplane interface.
– Power off disable outputs permit “live insertion”
The FCT162244T/AT/CT/ET have balanced output current
– Typical VOLP (Output Ground Bounce) < 1.0V at
levels and current limiting resistors. These offer low ground
VCC = 5V, TA = 25°C
bounce, minimal undershoot, and controlled output fall times,
• Features for FCT162244T/AT/CT/ET:
reducing the need for external series terminating resistors
– Balanced Output Drivers: ±24mA (commercial),
while still providing very high speed operation for loads of less
±16mA (military)
than 200pF.
– Reduced system switching noise
The FCT166244T/AT/CT are suited for very low noise,
– Typical VOLP (Output Ground Bounce) < 0.6V at
point-to-point driving where there is a single receiver, or a very
VCC = 5V,TA = 25°C
light lumped load (<100pF). The buffers are designed to limit
• Features for FCT166244T/AT/CT:

– Light Drive Balanced Output: ±8mA (commercial),
on the signal lines without using external series terminating

resistors.
– Minimal system switching noise
The FCT162H244T/AT/CT/ET have "Bus-Hold" which re-

• Features for FCT162H244T/AT/CT/ET:
need for pull-up/down resistors.
– Bus-Hold retains last active bus state during 3-state
– Eliminates the need for external pull up resistors
