No Preview Available !

FEATURES:
• Equivalent to ALS speeds and output drive over full tempera-
ture and voltage supply extremes
• 10ns typical clock to output
• IOL = 14mA over full military temperature range
• CMOS power levels (5p.W typo static)
• Both CMOS and TTL output compatible
• Substantially lower input current levels than ALS (5p.A max.)
• Octal D flip-flop with clear
• 100% product assurance screening to MIL-STD-883, Class B
is available
• JEDEC standard pinout for DIP and LCC
DESCRIPTION:
The IDT54/74AHCT273 are octal D flip-flops built using
advanced CEMOS'·, a dual metal CMOS technology. The
IDT54/74AHCT273 has eight edge-triggered D-type flip-flops
with individual D inputs and 0 outputs. The common buffered
Clock (CP) and Master Reset (MR) inputs load and reset (clear)
all flip-flops simultaneously.
Ihe register is fully edge-triggered. The state of each D input,
one setup time before the LOW-to-HIGH clock transition, is
transferred to the corresponding flip-flop's 0 output.
All outputs will be forced LOW independently of Clock or Data
inputs by a LOW voltage level on the MR input. The device is
useful for applications where the true output only is required and
the Clock and Master Reset are common to all storage elements.
