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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.

MIL-M-38510/3250

NOTES:

1.  O/C input pulse characteristics:  Vgen  = 3.0 ±0.2 V, tI  � 15 ns, tO  � 6 ns, tP(input)  � 200 ns, and PRR � 1 MHz.

2.  All diodes are 1N3064 or equivalent.

3.  For the standard test circuit, CL  = 50 pF ±10%.  For the alternate load circuit, CL  = 50 pF ±10%  for tPZL and tPZH

and CL  = 15 pF minimum for tPLZ  and tPHZ.  All capacitive load values include jig and probe capacitance.

4.  The diodes and resistors shown within the dotted area are optional.  When the diodes and resistors are used, VBIAS shall be 5.5 V for all tests except for tPHZ; for tPHZ tests, VBIAS shall be -0.6 V.

5.  When using the alternate load circuit, the appropriate switch positions for the three state tests are listed in the table below.
