DM74ALS03B Quad 2-Input NAND Gate with Open Collector Outputs
General Description
This device contains four independent gates, each of which performs the logic NAND function. The open-collector outputs require external pull-up resistors for proper logical operation. Pull-Up Resistor Equations
Features
s Switching specifications at 50 pF s Switching specifications guaranteed over full temperature and VCC range s Advanced oxide-isolated, ion-implanted Schottky TTL process s Functionally and pin for pin compatible with Schottky and low power Schottky TTL counterpart s 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
