DM74LS03 Datasheet Quad 2-input Nand Gates

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: 54LS03 DM54LS03 DM74LS03 Quad 2-Input NAND Gates with Open-Collector Outputs June 1989 54LS03 DM54LS03 DM74LS03 Quad 2-Input NAND Gates with Open-Collector.

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 RMAX e VCC (Min) b VOH N1 (IOH) a N2 (IIH)

Key Features

  • Y VCC (Max) b VOL RMIN e IOL b N3 (IIL) Where N1 (IOH) e total maximum output high current for all outputs tied to pull-up resistor N2 (IIH) e total maximum input high current for all inputs tied to pull-up resistor N3 (IIL) e total maximum input low current for all inputs tied to pull-up resistor Alternate Military Aerospace device (54LS03) is available Contact a National Semiconductor Sales Office Distributor for specifications Connection Diagram Dual-In-Line Package TL F 6344.
