DM7407
Hex Buffers with High Voltage Open-Collector Outputs
General Description
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.
Pull-Up Resistor Equations
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
