DM5406/DM7406 Hex Inverting Buffers with High Voltage Open-Collector Outputs

June 1989

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.

Pull-Up Resistor Equations

RMAX eVO(Min) bVOH

N1(IOH)aN2(IIH)

RMIN eVO(Max) bVOL

IOL bN3(IIL)

Where: N1(IOH)etotal maximum output high current for all

outputs tied to pull-up resistor

N2(IIH)etotal maximum input high current for all

inputs tied to pull-up resistor

N3(IIL)etotal maximum input low current for all

inputs tied to pull-up resistor

Note:

The ‘‘Absolute Maximum Ratings’’ are those values

beyond which the safety of the device cannot be guaran-

teed. The device should not be operated at these limits. The

parametric values defined in the ‘‘Electrical Characteristics’’

table are not guaranteed at the absolute maximum ratings.

The ‘‘Recommended Operating Conditions’’ table will define

the conditions for actual device operation.
