MIL-M-38510-343 Microcircuits, Digital, Bipolar, Advanced Schottky Ttl, Binary Counters, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, advanced Schottky TTL, binary counter microcircuits. Two product assurance classes and a choice of case outlines and lead finishes are provided or 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.
