MIL-M-38510-28 Microcircuits, Digital, Ttl, Low Power Shift Registers, Monolithic SiliconThis specification covers the detail requirements for monolithic, silicon, TTL, low power shift register, microcircuits. 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

MIL-M-38510/28C

Device types 02 and 05

H = high level (steady state), L = low level (steady state), x = irrelevant (any input, including transitions).

t = transition from low to high level.

QAO, QBO, QHO = the level of QA, QB, or QH, respectively,

before the indicated steady state input conditions were established.

QAn, QGn, = the level of QA or QG, respectively, before the most recent transition of the clock; indicates a one bit shift.

Typical clear, shift, and clear sequences.
