scope:

This specification covers the detail requirements for monolithic silicon, programmable read-only memory microcircuits which employ thin film nichrome (NiCr) resistors, tungsten (W), or titanium-tungsten (TiW) as the fusible link or programming element. Two product assurance classes and a choice of case outlines and lead finishes are provided for each type and are reflected in the part number. A special test requirement is included in this specification to screen against devices which may contain excess moisture in the package materials or internal atmosphere (see freeze-out test of 4.2d).

The part number shall be in accordance with MIL-M-38510

The device type shall be as follows:

Device type Circuit 01, 03 256 word/4 bits per word PROM with uncommitted collector 02, 04 256 word/4 bits per word PROM with active pull-up and a third high impedance state output.

The device class shall be the product assurance level as defined in MIL-M-38510.

The case outline shall be designated as follows:
