MIL-M-38510-9 Microcircuits, Digital, Bipolar Ttl, Shift Registers, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, TTL, 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.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-3851O/9E

Device type O5

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

t  = transition from low to high level.

a, b, c, d = the level of steady state input at inputs A, B, C, or D, respectively.

QAO, QBO, QCO, QDO  = the level of QA, QB, QC  or QD  respectively, before the indicated steady state input conditions were established.

QAn, QBn, QCn, QDn  = the level of QA, QB, QC  or QD  respectively, before the most recent   t  transition of the clock.

Device type O6

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

t  = transition from low to high level.

a, b, c, d = the level of steady state input at inputs A, B, C, or D, respectively.

QAO, QBO, QCO, QDO  = the level of QA, QB, QC  or QD  respectively, before the indicated steady state input conditions were established.

QAn, QBn, QCn, QDn  = the level of QA, QB, QC  or QD  respectively, before the most recent   t  transition of the clock.
