INTERFACE REGISTER
DESCRIPTION:
FEATURES:
• A and C grades
The FCT823T series is built using an advanced dual metal CMOS
technology. The FCT823Tseries bus interface registers are designedto
eliminate the extra packages required to buffer existing registers and
provide extra data width for wider address/data paths or buses carrying
parity. The FCT823T is a 9-bit wide buffered register with Clock Enable
(EN)andClear(CLR)–idealforparitybus interfacinginhigh-performance
microprogrammedsystems.
• 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 the SOIC and QSOP packages
