DESCRIPTION:

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.

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 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

bipolar Am29800 series (5μA max.)

? Product available in Radiation Tolerant and Radiation

Enhanced versions

? Military product compliant to MIL-STD-883, Class B
