Perfect for the do-it-yourself vintage system enthusiast, the 23XX Adapter converts JEDEC standard 28 pin EPROM, EEPROM, or FLASH ROMs to a 2316,2332, or 2364 socket. Since 23XX ROMs could be produced with active-high or active-low select lines, The 23XX adapter can be configured for either signal level on any applicable select line. The optional 5 highest address lines are available via pads complete with provision for pullup resistors (4.7K).
The onboard 74hct138 3-to-8 decoder converts any combination of the 3 possible chip select lines into a single JEDEC standard select line. If a 23XX select line is not needed, that input can be tied to ground via SMT pads on the bottom of the PCB.
Construction details and configuration settings are available on the product information page.
