DM7400

Quad 2-Input NAND Gates

General Description

This device contains four independent gates each of which performs the logic NAND function.

Ordering Code:

Order Number	Package Number	Package Description
DM7400M	M14A	14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow
DM7400N	N14A	14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

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	5.5V	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.
