scope:

This specification covers the requirements for monolithic silicon, low-power Schottky TTL, latches. 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.

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

The device type shall be as follows:

Device type Circuit 01 4-bit cascadable bistable latch 02 Quad cascadable [S bar] - [R bar] latch 03 8-bit cascadable addressable latch 04 4-bit cascadable bistable latch 05 8-bit cascadable addressable latch

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

The case outline shall be designated as follows:

Letter Case outline (see MIL-M-38510, appendix C) E D-2 (16-lead, ¼" × ⅞"), dual-in-line package F F-5 (16-lead, ¼" × ⅜"), flat package 2 C-2 (20-terminal, .350" × .350"), square chip carrier package X C-2A (20-terminal, .350" × .350"), square chip carrier package
