TRANSMITTER ELECTRICAL CHARACTERISTICS 1
VCC = 5.0V ±10%
-55°C < TC < +125°C
Notes:
1.All tests guaranteed per test figure 6.
2.Guaranteed by device characterization. Capacitance is measured only for initial qualification and after any process or design changes which may affect
input or output capacitance.
3. For MIL-STD-1760, 22 Vp-p, L-L min.
4. Test in accordance with the method described in MIL-STD-1553B output symmetry, section 4.5.2.1.1.4.
5. Guaranteed to the limits specified if not tested.
