MIL-M-38510-383 Microcircuits, Digital, Bipolar, Advanced Low Power Schottky Ttl, Octal Buffer Gates With Three State Outputs, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, TTL, advanced low power Schottky, octal bus buffer gates with three state outputs. 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.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-38510/3838

NOTES:

1. All input pulses are supplied by generators having the following characteristics: t1 = t0 = 6 ±1.5 ns, PRR ≤ 1 MHz, ZOUT � 50 n.

2. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the

output control. Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.

3. In the examples above, the phase relationships between inputs and outputs have been chosen arbitrarily.

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

5. R1 = R2 = 499n ±1%.

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