IDT74FCT163646/A/C  
3.3V CMOS  
16-BIT BUS TRANSCEIVER/  
REGISTERS  
Integrated Device Technology, Inc.  
FEATURES:  
DESCRIPTION:  
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 inde-  
pendant 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. Flow-  
through 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.  
• 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
