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
