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

outputs require external pull-up resistors for proper logical

operation.

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 for

all inputs tied to pull-up resistor

N3 (IIL) = total maximum input low current for

all inputs tied to pull-up resistor
