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)
IIN ......................................................Current flowing into an input terminal
tHZ .....................................................Output disable time (of a three-state output) 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.
tLZ .....................................................Output disable time (of a three-state output) 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.
tZH ...................................................................Output enable time (of a three-state output) to high level. The time
between the specified reference points on the input and output voltage
waveforms with the three-state output changing forma high impedance
(off) state to the defined high level.
tZL ....................................................................Output enable time (of a three-state output) to low level. The time
between the specified reference points on the input and output voltage
waveforms with the three-state output changing forma high impedance
(off) state to the defined low level.
VIN .....................................................Voltage level at an input terminal
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.
