DM74S03 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
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 DM74S03MX Package Number M14A Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150 Narrow
This device is only available in Tape and Reel.
