MIL-M-38510-208 Microcircuit, Digital, 4096-Bit Schottky, Bipolar, Programmable Read-Only Memory Prom, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, programmable read-only memory PROM microcircuits which employ thin film nichrome NiCr resistors, titanium-tungsten TiW, or zapped vertical emitter ZVE as the fusible link or programming element. Two product assurance classes and a choice of case outlines and lead finishes are provided and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.
