MIL-M-38510-360 Microcircuits, Digital, Bipolar, Low Power Schottky Ttl, Priority Encoders, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, low power Schottky TTL, priority encoder, logic microcircuits. Two product assurance classes and a choice of case outlines and lead finishes are provided 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.

MIL-M-38510/360B

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

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

VIN  .......................................... Voltage level at an input terminal

tPHZ  ......................................... 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.

tPLZ  ......................................... 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.

tPZH  ......................................... 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 from a high impedance

(off) state to the defined high level.

tPZL  ......................................... 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 from a high impedance (off) state to the defined low level.

IOZH ......................................... Output current in the high impedance mode with the output voltage high. IOZL  ......................................... Output current in the high impedance mode with the output voltage low.

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.

6.8  Manufacturers' designation.  Manufacturers' circuits which form a part of this specification are designated with an "x" as shown in table IV herein.

6.9  Changes from previous issue.  Marginal notations are not used in this revision to identify changes with respect to the previous issue due to the extensiveness of the changes.
