MIL-M-38510-206 Microcircuit, Digital, 4096 Bit Schottky, Bipolar, Programmable Read-Only Memory PromThis specification covers the detail requirements for monolithic silicon, programmable read-only memory PROM 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 and are reflected in the complete 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. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

1. NA = Not applicable.

2. x = Input may be high level, low level, or open circuit.

3. oc = open circuit (high resistance output).

4. Program readout can only be accomplished with both enable inputs at low level.

5. The outputs for an unprogrammed device shall be high for circuits A, and D, and shall be low for circuit B, c, and G.
