DM74LS02

Quad 2-Input NOR Gate

General Description

This device contains four independent gates each of which performs the logic NOR function.

Ordering Code:

Order Number	Package Number	Package Description
DM74LS02M	M14A	14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150 Narrow

Absolute Maximum Ratings(Note 1)

	Supply Voltage	7V	Note 1: The “Absolute Maximum Ratings” are those values beyond which
			the safety of the device cannot be guaranteed. The device should not be
	Input Voltage	7V	operated at these limits. The parametric values defined in the Electrical
			Characteristics tables are not guaranteed at the absolute maximum ratings.
	Operating Free Air Temperature Range	0°C to +70°C
			The “Recommended Operating Conditions” table will define the conditions
	Storage Temperature Range	−65°C to +150°C	for actual device operation.
