High Speed CMOS Synchronous Presettable Binary Counter

No Preview Available !

FEATURES:
• Equivalent to ALS speeds and output drive over full
temperature and voltage supply extremes
• IOL = 14mA over full military temperature range
• CMOS power levels (51'W typo static)
• 80th CMOS and TTL output compatible
• Substantially lower input current levels than ALS (51' max)
• 100% product assurance screening to MIL-STD-883, Class 8
is available
• JEDEC standard pinout for DIP and LCC
DESCRIPTION:
The IDT54174AHCT1611163 are high-speed synchronous
modul0-16 binary counters built using advanced CEMOS'·, a
dual metal CMOS technology. They are synchronously preset-
table for application in programmable dividers and have two
types of Count Enable inputs plus a Terminal Count output for
versatility in forming synchronous multistage counters. The
IDT54174AHCT161/163 have asynchronous Master Reset inputs
that override all other inputs and force the outputs LOW. The
IDT54/74AHCT161/163 have Synchronous Reset inputs that
override counting and parallel loading and allow the outputs to
be simultaneously reset on the rising edge of the clock.

NOTE:
1. Stresses greaterthan 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.
