MIL-M-38510-328 Microcircuits, Digital, Bipolar, Low-Power Schottky Ttl, Bus Transceivers With Three State Outputs, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, low-power Schottky TTL, bus transceivers 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.

NOTES:

1. RL = 110n ± 5%

2. All diodes are 1N3064 or equivalent.

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

4. The pulse generators have the following characteristics: Vgen = 3.0 V, PRR ≤ 1 MHz, tTLH ≤ 15 ns, tTHL ≤ 6 ns

ZOUT = 50n.

5. Clock pulse characteristics: tP(CLK) = 20 ns, tSETUP = 20 ns.

6. 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 -0.6V.
