+5V-Powered, Multichannel RS-232

Drivers/Receivers

ELECTRICAL CHARACTERISTICS—MAX225/MAX244–MAX249 (continued)

(MAX225, VCC= 5.0V ±5%; MAX244–MAX249, VCC= +5.0V ±10%, external capacitors C1–C4 = 1µF; TA= TMINto TMAX; unless oth-erwise noted.)

Note 7:The 300Ωminimum specification complies with EIA/TIA-232E, but the actual resistance when in shutdown mode or VCC=

0V is 10MΩas is implied by the leakage specification.
