Product Summary

The 95MS14 is a Plug n Play Front-End Device for ISA-Bus System. The 95MS14 includes the necessary state machine logic to manage the Plug n Play protocol in addition to switches for steering Interrupt and DMA requests. The 95MS14 also features a built-in 2k bits of serial EEPROM for storing the resource data specified in the Plug n Play Standard. In addition, 4k bits of EEPROM is available for use by other onboard logic.
