MIL-M-38510-21 Microcircuits, Digital, Bipolar, Ttl, Low Power, Flip-Flops, Monolithic SiliconThis specification covers the detail requirements for monolithic, silicon, TTL, low power, 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

MIL-M-38510/21F

Device type 05

Positive logic:     Low input to preset sets Q to high level Low input to clear sets Q to low level Preset and clear are independent of clock

NOTES:

1.  tn = Bit time before clock pulse.

2.  tn+1 = Bit time after clock pulse.

Description for device type 05

Input information is transferred to the output on the positive edge of the clock pulse.  Clock triggering occurs at a voltage level of the clock pulse and is not directly related to the transition time of the positive going pulse.  After the clock input threshold voltage has been passed, the data input (D) is locked out.
