DM7406 Hex Inverting Buff ers wi th High Voltage Open-Collector Outputs

DM7406

Hex Inver ti n g Bu f f e rs

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

output s require exter nal pull-up r esistors for pr oper logical

operation.

Pull-Up Resistor Equations

Where: N1 (IOH) = total maximum output high current

for all outputs tied to pull-up resistor

2 (IIH) = total maximu m inp ut hig h cur ren t for

all inputs tied to pull-up resistor

N3 (IIL) = total maximum input low current for

all inputs tied to pull-up resistor

Ordering Code:

Devices also available in Tape and Reel. Speci fy by appe nding the s uffix let t er “X” to the o rdering code.

Absolute Maximum Ratings(Note 1) Note 1: The “Absolute Maximum Ratings” are those v alues beyon d which

the saf ety of the device cannot be gu aranteed. Th e device shoul d not be

operated at these limits. The parametric values defined in the Electrical

Characteristics tables are not guaranteed at the absolute maximum ratings.

The “R ecomm ended Oper ating Co ndition s” table will def ine the condit ions

for actu al device operation.
