scope:

This specification covers the detail requirements for monolithic silicon, advanced Schottky TTL, Octal buffer (3-state) microcircuits. Two product assurance classes and a choice of case outlines and lead finishes are provided and are reflected in the part number.

The part number shall be in accordance with MIL-M-38510.

The device types shall be as follows:

Device type Circuit 01 Octal buffer with active low enabled 3-state inverted outputs 02 Octal buffer with active low and active high enabled 3-state noninverted outputs 03 Octal buffer with active low enabled 3-state noninverted outputs 04 Octal buffer with active low enabled 3-state inverted outputs (inputs and outputs opposite side of package)

The device class shall be the product assurance level as defined in MIL-M-38510.

The case outlines shall be designated as follows:

Outline letter Case outline (see MIL-M-38510, appendix C) R D-8 (20-lead, ¼" × 1 1/16"), dual-in-line package S F-9 (20-lead, ¼" × ½"), flat package X C-2A (20-terminal, .350" × .350") square chip carrier package 2 C-2 (20-terminal, .350" × .350") square chip carrier package
