DM74ALS03B

Quad 2-Input NAND Gate with Open Collector Outputs

	General Description		Features
	This device contains four independent gates, each of which		■ Switching specifications at 50 pF
	performs the logic NAND function. The open-collector out-		■ Switching specifications guaranteed over full tempera-
	puts require	external pull-up resistors for proper logical
			ture and VCC range
	operation.
			■ Advanced oxide-isolated, ion-implanted Schottky TTL
	Pull-Up Resistor Equations
			process
			■ Functionally and pin for pin compatible with Schottky
			and low power Schottky TTL counterpart
			■ Improved AC performance over Schottky and low power
			Schottky counterparts
	Where:	N1 (IOH) = total maximum output HIGH current
		for all outputs tied to pull-up resistor

N2 (IIH) = total maximum input HIGH current for all inputs tied to pull-up resistor

N3 (IIL) = total maximum input LOW current for all inputs tied to pull-up resistor

Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation.
