MIL-M-38510/383B
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:
GND ............................................
Ground zero voltage potential
VIN ...............................................
Voltage level at an input terminal
IIN .................................................
Current flowing into an input terminal
tPHZ ..............................................
Output disable time from high level - The time between the specified
reference points on the input and output voltage waveforms with the three
state output changing from the defined high level to a high impedance
(off) state.
tPLZ ..............................................
Output disable time from low level - The time between the specified
reference points on the input and output voltage waveforms with the three
state output changing from the defined low level to a high impedance
(off) state.
tPZH ..............................................
Output enable time to high level - The time between the specified
reference points on the input and output voltage waveforms with the three
state output changing from high impedance (off) state to the defined high
level.
tPZL ..............................................
Output enable time to low level - The time between the specified
reference points on the input and output voltage waveforms with the three
state output changing from high impedance (off) state to the defined low
level.
IOZL ..............................................
Output current in the high impedance mode with the output voltage low.
IOZH ..............................................
Output current in the high impedance mode with the output voltage high.
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), lead material
and finish A (see 3.4). 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 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.
