DM5438DM7438 Quad 2-Input NAND Buffers

with Open-Collector Outputs

General Description

This device contains four independent gates each of which

performs the logic NAND function The open-collector out-

puts require external pull-up resistors for proper logical op-

eration

Pull-Up Resistor Equations

RMAX e

VCC (Min) b VOH

N1 (IOH) a N2 (IIH)

RMIN e

VCC (Max) b VOL

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
