IDT74FCT163244/A/C
3.3V CMOS 16-BIT
BUFFER/LINE DRIVER
Integrated Device Technology, Inc.
FEATURES:
• 0.5 MICRON CMOS Technology
DESCRIPTION:
The FCT163244/A/C 16-bit buffer/line drivers are built
using advanced dual metal CMOS technology. These high-
speed, low-power devices offer bus/backplane interface ca-
pability with improved packing density. These devices have
a flow-through organization for simplifying board layout. The
three-state controls 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.
TheinputsoftheFCT163244/A/Ccanbedrivenfromeither
3.3V or 5V devices. This feature allows the use of these
devices as translators in a mixed 3.3V/5V supply system.
Thus, the FCT163244/A/C can be used as buffers to connect
5V components to a 3.3V bus.
• 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
• 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
