DESCRIPTION:
IDT54/74FCT823A/B/C
• 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)
• I
OL
= 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.)
µ
• MIlitary product compliant to MIL-STD-883, Class B
• Available in the following packages:
– Commercial: SOIC
– Military: CERDIP, LCC
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.
The FCT823 high-performance interface family is designed for high-
capacitance load drive capability, while providing low-capacitance bus
loading at both inputs and outputs. All inputs have clamp diodes and all
outputs are designed for low-capacitance bus loading in high-impedance
state.
