MIL-M-38510-312 Microcircuits, Digital, Low-Power Schottky Ttl, 4-Bit Binary Full Adders With Fast Carry, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, low-power Schottky TTL, 4-bit binary full adders with fast carry. 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.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-38510/312C

NOTES:

1. The pulse generator has the following characteristics: PRR ≤ 1.0 MHz, tTLH ≤ 15 ns, tTHL ≤ 6 ns, tP = 200 ns and ZOUT 50ν.

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

3. All diodes are 1N3064 or equivalent.

4. RL = 2.0 kν ±5%.

5. Load circuit on a given output are only required when specified by "OUT" on the specific test in table III. Load

circuits may otherwise be omitted.
