MIL-M-38510-505 Microcircuits, Digital, Bipolar Programmable Logic, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, bipolar, programmable logic microcircuits which employ titanium tungsten resistors as the fusible link or programming element. Two product assurance classes B and S and a choice of case outlines and lead finishes are provided and are reflected in the complete part or identifying number PIN. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

6.6 Logistic support. Lead materials and finishes (see 3.4) are interchangeable. Unless otherwise specified, microcircuits acquired for Government logistic support will be acquired to device class B (see 1.2.2) and lead material and finish A (see 3.4). Longer length leads and lead forming will not affect the part number. It is intended that spare devices for logistic support be acquired in the unprogrammed condition (see 3.8.1) and programmed by the maintenance activity, except where use of quantities for devices with a specific program or pattern justify stocking of preprogrammed devices.

6.7 Substitutability. The cross-reference information below is presented for the convenience of users. Microcircuits covered by this specification will functionally replace the listed generic industry type. Generic industry microcircuit types may not have equivalent operational performance characteristics across military temperature

ranges or reliability factors equivalent to MIL-M-38510 device types and may have slight physical variations in relation to case size. The presence of this information should not be deemed as permitting substitution of generic industry

types for MIL-M-38510 types or as a waiver of any of the provisions of MIL-PRF-38535.
