DM7406

Hex Inverting Buffers

with High Voltage Open-Collector Outputs

General Description

This device contains six independent buffers each of whichperforms the logic INVERT function. The open-collectoroutputs require external pull-up resistors for proper logicaloperation.

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 forall inputs tied to pull-up resistor

N3 (IIL) = total maximum input low current forall inputs tied to pull-up resistor

Note 1: The “Absolute Maximum Ratings” are those values beyond whichthe safety of the device cannot be guaranteed. The device should not beoperated at these limits. The parametric values defined in the ElectricalCharacteristics tables are not guaranteed at the absolute maximum ratings.The “Recommended Operating Conditions” table will define the conditionsfor actual device operation.
