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 Package Number Package Description DM7438M M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow DM7438N N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide 7438SJ M14D 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide Devices also available in Tape and Reel.
