DESCRIPTION:

• A and C grades

TheFCT2652Tconsistsofabustransceiverwith3-stateD-typeflip-flops

andcontrolcircuitryarrangedformultiplexedtransmissionofdatadirectly

from the data bus or from the internal storage registers. The FCT2652T

utilizes GAB and GBAsignals to control the transceiver functions.

SABandSBAcontrolpinsareprovidedtoselecteitherreal-timeorstored

data transfer. The circuitry used for select control will eliminate the typical

decoding glitch that occurs in a multiplexer during the transition between

storedandreal-timedata.Alowinputlevelselectsreal-timedataandahigh

selectsstoreddata.

• Low input and output leakage ≤1µA (max.)

• CMOS power levels

• True TTL input and output compatibility:

– VOH = 3.3V (typ.)

– VOL = 0.3V (typ.)

• Resistor outputs (-15mA IOH, 12mA IOL)

• Meets or exceeds JEDEC standard 18 specifications

• Reduced system switching noise

• Power off disable outputs permit "live insertion"

• Available in SOIC and QSOP packages

Data on the A or B data bus, or both, can be stored in the internal D flip-

flops by low-to-high transitions at the appropriate clock pins (CPAB or

CPBA), regardless of the select or enable control pins.

The FCT2652T have balanced drive outputs with current limiting

resistors. This offers low ground bounce, minimal undershoot and con-

trolled output fall times-reducing the need for external series terminating

resistors. FCT2652T parts are plug-in replacements for FCT652T parts.
