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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.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. Enable input pulse characteristics for tPLH2 and tPHL2: Vgen = 3.0 ±0.2 V, tO � 6 ns, tI � 15 ns, t(enable) = 15 ns, and

PRR � 1 MHz.

2. All diodes are 1N3064 or equivalent.

3. CL = 50 pF ±10% (including probe and jig capacitance).

4. The diode and resistor shown within the dotted area are optional. When the diode and resistor are used, VBIAS

shall be 5.5 V for all tests except for tPHZ; for tPHZ tests, VBIAS shall be -0.6 V.

5. Switches S1 and S2 are closed for tPLH2 and tPHL2, when using the alternate load circuit.
