High Speed CMOS Octal D Register

No Preview Available !

FEATURES:
• Equivalent to ALS speeds and output drive over full
temperature and voltage supply extremes
• 10ns typical address to output delay
• 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 register (3-state)
• 100% product assurance screening to MIL-STD-833, Class B
is available
• JEDEC standard pinout for DIP and LCC
DESCRIPTION:
The IDT54/74AHCT374 are 8-bit registers built using advanced
CEMOS'", a dual metal CMOS technology. This register consists
of eight D-type flip-flops with a buffered common clock and
bu~ered three-state output control. When the output enable (OE)
inp~t is LOW, the eight outputs are enabled. When the OE input is
HIGH, the outputs are in the three-state conditions.
Input data meeting the set-up and hold time requirements of
the D inputs is transferred to the 0 outputs on the LOW-to-HIGH
transition of the clock input.

NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS
may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above
those indicated in the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended periods may
affect reliability.
