FEATURES:
DESCRIPTION:
• Common features:
– 0.5 MICRON CMOS Technology
– High-speed, low-power CMOS replacement for
ABT functions
– Typical tSK(o) (Output Skew) < 250ps
– Low input and output leakage ≤1µA (max.)
– 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%
• Features for FCT16240T/AT/CT/ET:
– High drive outputs (-32mA IOH, 64mA IOL)
– Power off disable outputs permit “live insertion”
– Typical VOLP (Output Ground Bounce) < 1.0V at
VCC = 5V, TA = 25°C
• Features for FCT162240T/AT/CT/ET:
– Balanced Output Drivers: ±24mA (commercial),
±16mA (military)
– Reduced system switching noise
– Typical VOLP (Output Ground Bounce) < 0.6V at
VCC = 5V,TA = 25°C
The FCT16240T/AT/CT/ET and FCT162240T/AT/CT/ET
16-bit buffer/line drivers are built using advanced dual metal
CMOS technology. These high-speed, low-power devices
offer bus/backplane interface capability with improved packing
density. The flow-through organization of signal pins simplifies
layout. The three-state controls are designed to operate these
devices in a Quad-Nibble, Dual-Byte or single 16-bit word
mode. All inputs are designed with hysteresis for improved
noise margin.
The FCT16240T/AT/CT/ET are ideally suited for driving
high capacitance loads and low-impedance backplanes. The
output buffers are designed with power off disable capability
to allow "live insertion" of boards when used as backplane
drivers.
The FCT162240T/AT/CT/ET have 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. The
FCT162240T/AT/CT/ET are plug-in replacements for
FCT16240T/AT/CT/ET and 54/74ABT16240 for on-board interface applications.
