description
These devices contain six independent 2-input
NAND
drivers.
They
perform
the
Boolean
functions Y = A
B or Y = A+B in positive logic.
The
center
pin
configuration
used
in
the
’ALS1804A and ’AS1804 provides a reduction of
lead inductance when compared to the ’ALS804A
and ’AS804B. This reduction of lead inductance
will minimize noise generated onto either the VCC
or GND bus. This reduction is significant in high
current switching applications.
The SN54ALS1804A and SN54AS1804 are
characterized for operation over the full military
temperature range of – 55
°C to 125°C. The
SN74ALS1804A and SN74AS1804 are charac-
terized for operation from 0
°C to 70°C.
