DM7438 Datasheet Quad 2-input Nand Buffers With Open-collector Outputs

Manufacturer: Fairchild (now onsemi)

Overview: DM7438 • 7438 Quad 2-Input NAND Buffers with Open-Collector Outputs September 1986 Revised February 2000 DM7438 • 7438 Quad 2-Input NAND Buffers 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.

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