DM74LS03

Quad 2-Input NAND Gates with Open-Collector Outputs

General Descript ion

This device contains four independent gates each of which

performs the logic NAND functio n. The op en-colle ctor out-

puts require external pull-up resistors for proper logical

operation.

Pull-Up Resistor Equations

Where: N1 (IOH) = total ma ximum output high curr ent

for all outputs tied to pull-up resistor

2 (IIH) = total maximum inp ut high cur ren t for

all inputs tied to pull-up re sistor

N3 (IIL) = total maximum input low current for

all inputs tied to pull-up re sistor

Ordering Code:

Devices also available in Tape and R eel. Speci fy by appending the s uffix let t er “X” to the orderin g c ode.

Absolute Maximum Ratings(Not e 1) Note 1: The “Absolute Maximum Ratings” are those values beyond which

the saf ety of the device cannot be guarante ed. The device s hould not be

operated at these limits. The parametric values defined in the Electrical

Characteristics tables are not gua rant eed at the absolute maximum rati n gs.

The “Re comme nded Operat ing Co ndition s” table will define the cond itions

for actu al device operation.
