Description
The IDT70121/IDT70125 are high-speed 2K x 9 Dual-Port STATIC RAMs. The IDT70121 is designed to be used as a stand-alone 9-bit Dual- Port RAM or as a “MASTER” Dual-Port RAM together WITH the IDT70125 “SLAVE” Dual-Port in 18-bit-or-more word width systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 18-bit-or-wider memory system applications results in full-speed, error-free operation WITHout the need for additional discrete logic.

Product Highlights
Ripple attenuator modules may be connected to VI-200 or VI-J00 converters, FlatPACs, MegaPACs, MasterModules or MegaModules, WITH output voltages from 5 to 50V, to limit output noise to less than 3mV peak-to-peak at loads up to 20A. Combining active and passive filtering, the VI-RAM attenuates both low frequency input power source fundamental and harmonics, and high frequency switching components in the frequency range of DC to 20 MHz, while exhibiting efficiencies of 93-99%. No adjustments are required, and remote sense and output voltage trim features are retained.
