FEATURES:
• 0.5 MICRON CMOS Technology
DESCRIPTION:
The FCT163827A/B/C 20-bit buffers are built using ad-
vanced dual metal CMOS technology. These 20-bit bus
drivers provide high-performance bus interface buffering for
wide data/address paths or busses carrying parity. Two pairs
of NAND-ed output enable controls offer maximum control
flexibility and are organized to operate the device as two 10-
bit buffers or one 20-bit buffer. Flow-through organization of
signal pins simplifies layout. All inputs are designed with
hysteresis for improved noise margin.
• Typical tSK(o) (Output Skew) < 250ps
• 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 and 15.7 mil pitch TVSOP
• Extended commercial range of -40°C to +85°C
• VCC = 3.3V ±0.3V, Normal Range or
VCC = 2.7 to 3.6V, Extended Range
The FCT163827A/B/C have series current limiting resis-
tors. This offers low ground bounce, minimal undershoot, and
controlled output fall times–reducing the need for external
series terminating resistors.
The inputs of the FCT163827A/B/C can be driven from
either 3.3V or 5V devices. This feature allows the use of these
devices as translators in a mixed 3.3V/5V supply system.
• CMOS power levels (0.4µW typ. static)
• Rail-to-Rail output swing for increased noise margin
• Low Ground Bounce (0.3V typ.)
• Inputs (except I/O) can be driven by 3.3V or 5V
