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

Where N₁ (I_OH) e total maximum output high current for all
outputs tied to pull-up resistor
N₂ (I_IH) e total maximum input high current for all
inputs tied to pull-up resistor
N₃ (I_IL) e total maximum input low current for all
inputs tied to pull-up resistor
