1700E, EL, D, L PROMs - What is the voltage level of my PROM - 3.3V or 5V?


Problem Description:

I have a 1700-Series PROM; how do I determine whether it is 3.3V or 5V?


All 1700L PROMs are 3.3V.

The 1700E family comes in both 5V and 3.3V versions:

1700E PROM parts are 5V; 1700EL parts are the 3.3V version.

Obsolete parts: 1700D parts are 5V.
