22V10 PAL Pin Clarification

Different Manufacturers use different names for the pins on programmable logic parts. In the schematics for industrial temperature physical layer repeaters using the FTT-10A transceiver, Echelon has used pin names similar to those of Cypress Semiconductor’s PALs.

(Note: Avoid using PALC22V10 parts – we found that they were very susceptible to soft latchup during ESD testing.)
