DM74S03
Quad 2-Input NAND Gate with Open-Collector Outputs
DM74S03 Quad 2-Input NAND Gate with Open-Collector Outputs
General Description
This device contains four indep en den t ga tes ea ch of w hich
performs the logic N AND functio n. 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
N
for all outputs tied to pull-up resistor
(IIH) = total maximum input H IGH current
2
for all inputs tied to pull-up resistor
N
(IIL) = total maximum input LOW current for
3
all inputs tied to pull-up resistor

DM74S03
Output Voltage 7V
Operating Free Air Temperature Range 0°C to +70°C
Storage Temperature Range −65°C to +150°C
Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the d evice cannot be guaranteed. The device sh ould not be
operated at these limit s. The parametric values defin ed in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommend ed O peratin g Cond itions ” table will defin e the c ondit ions
for actual device operation.
