DM7407
Hex Buffers with High Voltage Open-Collector Outputs
General Description
Pull-Up Resistor Equations
This device contains six independent gates each of which
performs a buffer function. The open-collector outputs
require external pull-up resistors for proper logical opera-
tion.
Where:
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

Absolute Maximum Ratings(Note 1)
Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
