AC CHARACTERISTICS
Note 7: All units production tested at hot. Specifications over temperature are guaranteed by design.
Note 8: The 300
Ω minimum specification complies with EIA/TIA-232E, but the actual resistance when in shutdown mode or VCC =
0V is 10M
Ω as is implied by the leakage specification.
ELECTRICAL CHARACTERISTICS—MAX225/MAX244–MAX249 (continued)
(MAX225, VCC = +5.0V ±5%; MAX244–MAX249, VCC = +5.0V ±10%, external capacitors C1–C4 = 1F; TA = TMIN to TMAX; unless
otherwise noted.) (Note 7)
