APPLICATION NOTE 4571
Simple Nonvolatile Gating
By:Reinhardt Wagner


Abstract:As an alternative to the use of PALs, GALs, or CPLD devices to implement a non-volatile gating function, these circuits
store the gating signal (block or transmit) using a digital potentiometer (MAX5427 or MAX5527) controlled by a serial interface.

A similar version of this article appeared in the September 3, 2007 issue of EDN magazine.

The following describes a simple alternative to the non-volatile gating function typically implemented by a PAL, GAL, or CPLD
device. To "gate" a logic signal (to block or transmit it), you usually empl……
