MIL-M-38510-380 Microcircuits, Digital, Bipolar, Advanced Low Power Schottky Ttl, Binary Counters, Cascadable, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, advanced low power Schottky TTL, binary counters. 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.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-38510/3808

NOTES:

1.  Clock input pulse characteristics:  t1 = t0 = 6 ±1.5 ns; tP(CLOCK)  = 20 ns; PRR ≤ 1 MHz.

2.  For fMAX, the clock input pulse characteristics are as follows: t1  = t0 = 3 ±1.5 ns; for 25°C, tP(CLOCK) = 12.5 ns; PRR = 30 MHz; for -55/+125°C, tP(CLOCK) = 20 ns; PRR = 25 MHz.

3.  Enable input pulse characteristics:  t1 = t0 = 6 ±1.5 ns.

4.  Up/down input pulse characteristics:  t1 = t0  = 6 ±1.5 ns.

5.  Inputs not under test are at ground.

6.  CL  = 50 pF ±10%. including scope probe, wiring, and stray capacitance without package in test fixture.

7.  RL  = 499n ±1%.

8.  Voltage measurements are to be made with respect to network ground terminal.
