DM74LS38 Quad 2-Input NAND Buffer with Open-Collector Outputs

August 1986

Revised March 2000

DM74LS38

Quad 2-Input NAND Buffer 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

operation.

Pull-Up Resistor Equations

Where:

)

total maximum output high current

for all outputs tied to pull-up resistor

)

total maximum input high current for

all inputs tied to pull-up resistor

)

total maximum input low current for

all inputs tied to pull-up resistor
