Note 5: These parameters, although ensured over the recommended operating conditions, are not 100% tested in production.
Note 6: Tested at fOSC = 40kHz (RT = 3.6kW,CT = 0.01mF, RD =0W)
Note 7: Collector off-state quiescent current measured at pin 13 with outputs low for UC1525A and high for UC1527A.
