Integrated Device Technology, Inc.
FEATURES:
DESCRIPTION:

• 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 FCT163646/A/C 16-bit registered transceivers are
built using advanced dual metal CMOS technology. These
high-speed, low-power devices are organized as two independant 8-bit bus transceivers with 3-state D-type registers.
The control circuitry is organized for multiplexed transmission
of data between A bus and B bus either directly or from the
internal storage registers. Each 8-bit transceiver/register
features direction control (xDIR), over-riding Output Enable
control (xOE) and Select lines (xSAB and xSBA) to select
either real-time data or stored data. Separate clock inputs are
provided for A and B port registers. Data on the A or B data
bus, or both, can be stored in the internal registers by the
LOW-to-HIGH transitions at the appropriate clock pins. Flowthrough organization of signal pins simplifies layout. All inputs
are designed with hysteresis for improved noise margin.
The FCT163646/A/C have series current limiting resistors.
This offers low ground bounce, minimal undershoot, and
controlled output fall times-reducing the need for external
series terminating resistors.

NOTES:
1. See test circuit and waveforms.
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%.
