MIL-M-38510/755B
6.5 Abbreviations, symbols, and definitions. The abbreviations, symbols, and definitions used herein are defined in
MIL-PRF-38535, MIL-HDBK-1331, and as follows:
CIN ................................................ Input terminal-to-GND capacitance GND ............................................ Ground zero voltage potential ICC................................................. Quiescent supply current
IIL .................................................. Input current low
IIH.................................................. Input current high
TC ................................................ Case temperature
TA ................................................. Ambient temperature
VCC ............................................... Positive supply voltage
CPD ............................................... Power dissipation capacitance
VIC ................................................ Input clamp voltage
VGB ............................................... Ground bounce voltage
0/V............................................... Latch-up over-voltage
0/I ................................................ Latch-up over-current
tw .................................................. Trigger duration (width)
CI/0 ............................................... Input/output terminal-to-GND capacitance
6.6 Logistic support. Lead materials and finishes (see 3.5) are interchangeable. Unless otherwise specified, microcircuits acquired for Government logistic support will be acquired to device class S for National Aeronautics and Space Administration or class B for Department of Defense (see 1.2.2), lead material and finish A (see 3.5). Longer length leads 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, post irradiation performance 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.
