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 V
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.
