IDT54/74FCT821A/B/C IDT54/74FCT823A/B/C IDT54/74FCT824A/B/C IDT54/74FCT825A/B/C Features : - Equivalent to AMD’s Am29821-25 bipolar registers in pinout/function, speed and output drive over full temperature and voltage supply extremes - IDT54/74FCT821A/823A/824A/825A equivalent to FAST™ speed - IDT54/74FCT821B/823B/824B/825B 25% faster than FAST - IDT54/74FCT821C/823C/824C/825C 40% faster than FAST - Buffered mon Clock Enable (EN) and asynchronous Clear input (CLR) - IOL = 48m A (mercial) and 32m A (military) - Clamp diodes on all inputs for ringing suppression - CMOS power levels (1m W typ. static) - TTL input and output patibility - CMOS output level patible - Substantially lower input current levels than AMD’s bipolar Am29800 series (5µA max.) - Product available in Radiation Tolerant and Radiation Enhanced versions - Military product pliant to MIL-STD-883, Class B The IDT54/74FCT800 series is built using an advanced dual metal CMOS technology. The IDT54/74FCT820 series 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 IDT54/ 74FCT821 are buffered, 10-bit wide versions of the popular ‘374 function. The IDT54/74FCT823 and IDT54/74FCT824 are 9-bit wide buffered registers with Clock Enable (EN) and Clear (CLR) - ideal for parity bus interfacing in high-performance microprogrammed systems. The IDT54/74FCT825 are 8-bit buffered registers with all the ‘823 controls plus multiple enables (OE1, OE2, OE3) to allow multiuser control of the interface, e.g., CS, DMA and RD/WR. They are ideal for use as an output port requiring HIGH IOL/IOH. All of the IDT54/74FCT800 high-performance interface family are designed for high-capacitance load drive capability, while providing low-capacitance bus loading at both inputs and...
