MIL-M-38510-325 Microcircuits, Digital, Bipolar, Low-Power, Schottky Ttl, Flip-Flops, Cascadable, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, bipolar, low-power Schottky TTL, flip-flops, bistable logic 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.

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

x = irrelevant

r = transition from low to high level

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

Device type O2

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

x = irrelevant

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

z = high impedance state
