DESCRIPTION:
The FCT823 series is built using an advanced dual metal CMOS technology. The FCT823 bus interface registers are designed to eliminate the extra packages required to buffer existing registers and provide extra data width for wider address/data paths or buses carrying parity. The FCT823 is a 9-bit wide buffered register with Clock Enable (EN) and Clear (CLR) – ideal for parity bus interfacing in high-performance microprogram med systems.

FEATURES:
• Equivalent to AMD's Am29823 bipolar registers in pinout/function, speed, and output drive over full temperature and voltage supply extremes
• IDT54/74FCT823A equivalent to FAST™ speed
• IDT54FCT823B 25% faster than FAST
• IDT74FCT823C 40% faster than FAST
• Buffered common Clock Enable (EN) and Asynchronous Clear Input (CLR)
• IOL= 48mA (commercial) and 32mA (military)
• Clamp diodes on all inputs for ringing suppression
• CMOS power levels (1mW typ. static)
• TTL input and output compatibility
• CMOS output level compatible
• Substantially lower input current levels than AMD's bilopar Am29800 series (5µA max.)
• MIlitary product compliant to MIL-STD-883, Class B
• Available in the following packages:
– Commercial: SOIC
– Military: CERDIP, LCC
