scope:

This specification covers the detail requirements for monolithic silicon PROM microcircuits which employ thin film nichrome resistors (NiCr), titanium-tungsten (TiW), or zapped vertical emitter 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 part number. A special test requirement is included in this specification to screen against devices which may contain 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 Access times (ns) 01 4096 words/8 bits per word PROM with tri-state 45 outputs 02 4096 words/8 bits per word PROM with tri-state 85 outputs

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

The case outline shall be designated as follows:

Letter Case outline (see MIL-M-38510, appendix C J D-3 (24-lead, ½" × 1 ¼"), dual-in-line package 3 C-4 (28-terminal, .450" × .450"), square chip carrier package
