AC CHARACTERISTICS
Note 7: All units production tested at hot. Specifications over temperature are guaranteed by design.
Note 8: The 300
惟 minimum specification complies with EIA/TIA-232E, but the actual resistance when in shutdown mode or VCC =
0V is 10M
惟 as is implied by the leakage specification.
