MIL-M-38510-301 Microcircuits, Digital, Bipolar Low-Power Schottky Ttl, Flip-Flops, Cascadable, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, low-power Schottky TTL, flip-flops, bistable logic gate 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.

MIL-M-3851O/3O1F

DEVICE TYPES O3 AND 1O

H = high level (steady state) L = low level (steady state)

x = irrelevant

↓ = transition from high to low level

QO  = the level of Q before the indicated steady state input conditions were established.

TOGGLE: Each output changes to the complement of its previous level on each  ↓  clock transition.

*  This configuration is nonstable; that is, it will not persist when preset and clear inputs return to their inactive  (high) level.

DEVICE TYPE O4

H = high level (steady state) L = low level (steady state)

x = irrelevant

↓ = transition from high to low level

QO  = the level of Q before the indicated input conditions were established.

TOGGLE: Each output changes to the complement of its previous level on each  ↓  clock transition.
