DESCRIPTION:
FEATURES:
• A, B, and C grades
The IDT29FCT2052T is an 8-bit registered transceiver built using an
advanceddualmetalCMOStechnology.Two8-bitback-to-backregisters
store data flowing in both directions between two bidirectional buses.
Separateclock,clockenableand3-stateoutputenablesignalsareprovided
foreachregister. BothAoutputsandBoutputsareguaranteedtosink64mA.
The IDT29FCT2052T has balanced drive outputs with current limiting
resistors. This offers low ground bounce, minimal undershoot and con-
trolledoutputfalltimes-reducingthe needforexternalseries terminating
resistors. TheIDT29FCT2052Tisaplug-inreplacementfortheIDT29FCT52T.
• Low input and output leakage ≤1µA (max.)
• CMOS power levels
• True TTL input and output compatibility:
– VOH = 3.3V (typ.)
– VOL = 0.3V (typ.)
• High Drive outputs (-15mA IOH, 48mA IOL)
• Meets or exceeds JEDEC standard 18 specifications
• Power off disable outputs permit "live insertion"
• Available in SOIC and QSOP packages
