DM5407 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 re-
quire external pull-up resistors for proper logical operation
Pull-Up Resistor Equations

VO (Max) b VOL
IOL b N3 (IIL)
Where N1 (IOH) e total maximum output high current for all
outputs tied to pull-up resistor
N2 (IIH) e total maximum input high current for all
inputs tied to pull-up resistor
N3 (IIL) e total maximum input low current for all
inputs tied to pull-up resistor
