DM7416 Hex Inverting Buffers with High Voltage Open-Collector Outputs

August 1986
Revised February 2000

General Description

This device contain s six independe nt gates eac h of which
performs the logic INVERT function. The open-collector
outputs require exter nal pull-up r esistors for pr oper logical
operation.
