DESCRIPTION:

FEATURES:

TheFCT646Tconsistsofabustransceiverwith3-stateD-typeflip-flops

andcontrolcircuitryarrangedformultiplexedtransmissionofdatadirectly

from the data bus or from the internal storage registers. The FCT646T

utilizes the enable control (G) and direction (DIR) pins to control the

transceiverfunctions.

• Std., A, and C grades

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

• CMOS power levels

• True TTL input and output compatibility:

– VOH = 3.3V (typ.)

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.

– VOL = 0.3V (typ.)

• High Drive outputs (-15mA IOH, 64mA IOL)

• Meets or exceeds JEDEC standard 18 specifications

• Military product compliant to MIL-STD-883, Class B and DESC

listed (dual marked)

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.

• Power off disable outputs permit "live insertion"

• Available in the following packages:

– Industrial: SOIC, SSOP, QSOP, TSSOP

– Military: CERDIP, LCC
