MIL-M-38510-502 Microcircuits, Digital, Bipolar Field Programmable Logic Array Fpla 16 X 48 X 8, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, bipolar, field programmable logic array FPLA microcircuits which employ thin film nichrome resistors WICr as the fusible link or programming element. Three product assurance classes and a choice of case outline/lead material and finish are provided for each type and are reflected in the complete part number.

MIL-M-38510/502A

6.5  Abbreviations, symbols, and definitions.   The abbreviations, symbols, and definitions used herein are defined in MIL-PRF-38535 and MIL-HDBK-1331, and as follows:

GND .................................................. Electrical ground (common terminal) VIN  ..................................................... Voltage level at an input terminal. VIC......................................................Input clamp voltage.

IIN  ...................................................... Current flowing into an input terminal.

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 shall 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 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-35810 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.
