MIL-M-38510-21 Microcircuits, Digital, Bipolar, Ttl, Low Power, Flip-Flops, Monolithic SiliconThis specification covers the detail requirements for monolithic, silicon, TTL, low power, bistable logic microcircuits. Two product assurance classes and a choice of case outlines and lead finishes are provided for each type and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.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 3.3) are interchangeable.  Unless otherwise specified, microcircuits acquired for Government logistic support will be acquired to device class B (see 1.2.2), lead material and finish A (see 3.4).  Longer lead lengths and lead forming should not affect the part number.

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.
