MIL-M-38510-15 Microcircuits, Digital, Ttl, Bistable Latches, Monolithic SiliconThis specification covers the detail requirements for monolithic, silicon, TTL, 4-bit bistable latch 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

NOTES:

1. The D input pulse generator has the following characteristics: VGEN = 3 V, t1 = t0 ≤ 10 ns, PRR = 500 kHz at

50 % duty cycle. For subgroups 7 and 8, PRR ≤ 25 kHz at 50 % cuty cycle and PRR (D input) = 1/2 PRR (clock).

2. The clock pulse generator has the following characteristics: VGEN = 3 V minimum, t1 = t0 ≤ 10 ns, t(HOLD) =

tP(CLOCK) = 30 ns, t(SETUP) = 25 ns and PRR = 1 MHz. For subgroups 7 and 8, PRR ≤ 50 kHz.

3. Each latch is tested separately.

4. CL = 50 pF, which includes probe and jig capacitance.

5. RL = 390 n ±5%.

6. The Q waveforms are not applicable to device type 02.

7. All diodes are 1N3064 or equivalent.
