3.3V CMOS 16-BIT
BUFFER/LINE DRIVER
IDT74FCT163244/A/C
Integrated Device Technology, Inc.
FEATURES:
DESCRIPTION:
• 0.5 MICRON CMOS Technology
• 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
components
The FCT163244/A/C 16-bit buffer/line drivers are built
using advanced dual metal CMOS technology. These highspeed, low-power devices offer bus/backplane interface capability 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.
The inputs of the FCT163244/A/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.
Thus, the FCT163244/A/C can be used as buffers to connect
5V components to a 3.3V bus.

2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. Skew between any two outputs, of the same package, switching in the same direction. This parameter is guaranteed by design.
4. Propagation Delays and Enable/Disable times are with VCC = 3.3V ±0.3V, Normal Range. For VCC = 2.7V to 3.6V, Extended Range, all Propagation Delays
and Enable/Disable times should be degraded by 20%.
