TRANSCEIVER  
FEATURES:  
• 0.5 MICRON CMOS Technology  
DESCRIPTION:  
The FCT16952T 16-bit registered transceiver is built using advanced  
dual metal CMOS technology. These high-speed, low-power devices are  
organized as two independent 8-bit D-type registered transceivers with  
separateinputandoutputcontrolforindependentcontrolofdataflowineither  
direction. For example, the A-to-B Enable (xCEAB) must be low to enter  
datafromtheAport.xCLKABcontrolstheclockingfunction.WhenxCLKAB  
togglesfromlow-to-high, thedatapresentontheAportwillbeclockedinto  
theregister. xOEABperformsthe outputenablefunctionontheBport.Data  
flowfromtheBporttoAportissimilarbutrequiresusingxCEBA, xCLKBA,  
andxOEBAinputs. Full16-bitoperationisachievedbytyingthecontrolpins  
of the independent transceivers together.  
• High-speed, low-power CMOS replacement for ABT functions  
• Typical tSK(o) (Output Skew) < 250ps  
• Low input and output leakage 1µA (max.)  
• High drive outputs (-32mA IOH, 64mA IOL)  
• Power off disable outputs permit “live insertion”  
• Typical VOLP (Output Ground Bounce) < 1.0V at VCC = 5V,  
TA = 25°C  
• Available in SSOP and TSSOP packages
