High Speed CMOS Octal Buffer/Line Driver

No Preview Available !

FEATURES:
• Equivalent to ALS speeds and output drive over full tempera-
ture and voltage supply extremes
• 7ns typical data to output delay
• IOL = 14mA over full military temperature range
• CMOS power levels (5fJW typo static)
• 80th CMOS and TTL output compatible
• Substantially lower input current levels than ALS (5fJA max.)
• Octal buffer/line driver with 3-state output
• 100% product assurance screening to MIL-STD-883, Class 8
is available
• JEDEC standard pinout for DIP and LCC
DESCRIPTION:
The IDT54174AHCT240 is an octal buffer/line driver built using
advanced CEMOS~, a dual metal CMOS technology. The device
is designed to be employed as a memory and address driver,
clock driver and bus-oriented transmitter/receiver which provides
improved board density.
