Hex Buffers with High Voltage Open-Collector Outputs
DM7407 Hex Buffers with High Voltage Open-Collector Outputs
General Description
This device contain s six independe nt gates eac h of which
performs a buffer function. The open-collector outputs
require external pull-up resi stors for proper logical operation.
Pull-Up Resistor Equations
Where: N1 (IOH) = total maximum output high c urrent
