Revised February 2000 DM74ALS05A Hex Inverter with Open Collector Outputs General Description Features This device contains six independent gates, each of which performs the logic INVERT function. The open-collector outputs require external pull-up resistors for proper logical operation. ■ Switching specifications at 50 pF Pull-Up Resistor Equations ■ Switching specifications guaranteed over full temperature and VCC range ■ Advanced oxide-isolated, ion-implanted Schottky TTL 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 Ordering Code: Order Number Package Number Package Description DM74ALS05AM M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow DM74ALS05AN N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
