MIL-M-38510-328 Microcircuits, Digital, Bipolar, Low-Power Schottky Ttl, Bus Transceivers With Three State Outputs, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, low-power Schottky TTL, bus transceivers with three state outputs. 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.

MIL-M-38510/328C

6.3  Superseding information.  The requirements of MIL-M-38510 have been superseded to take advantage of the available Qualified Manufacturer Listing (QML) system provided by MIL-PRF-38535.  Previous references to MIL-M-

38510 in this document have been replaced by appropriate references to MIL-PRF-38535.  All technical requirements now consist of this specification and MIL-PRF-38535.  The MIL-M-38510 specification sheet number and PIN have been retained to avoid adversely impacting existing government logistics systems and contractor's parts lists.

6.4  Qualification.  With respect to products requiring qualification, awards will be made only for products which are, at the time of award of contract, qualified for inclusion in Qualified Manufacturers List QML-38535 whether or not such products have actually been so listed by that date.  The attention of the contractors is called to these requirements, and manufacturers are urged to arrange to have the products that they propose to offer to the Federal Government tested for qualification in order that they may be eligible to be awarded contracts or purchase orders for the products covered by this specification.  Information pertaining to qualification of products may be obtained from DSCC-VQ, 3990 E. Broad Street, Columbus, Ohio 43123-1199.

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 (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.

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-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.
