DM5406 DM7406 Hex Inverting Buffers with
High Voltage Open-Collector Outputs
General Description
This device contains six independent buffers each of which
performs the logic INVERT function The open-collector out-
puts require external pull-up resistors for proper logical op-
eration

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
