3 / 20 page www.ti.com ELECTRICAL CHARACTERISTICS UC1543 ,, UC1544 UC2543, UC2544 UC3543, UC3544 SLUS188A – APRIL 1997 – REVISED FEBRUARY 2007 Unless otherwise stated, these specifications apply for T A = -55°C to 125°C for theUC1543 and UC1544; -25°C to 85°C for the UC2543 and UC2544; and 0°C to 70°C for the UC3543 and UC3544. Electrical tests are performed with V IN = 10 V and 2-k Ω pull-up resistors on all indicator outputs. All electrical specifications for the UC1544, UC2544, and UC3544 devices are tested with the inverting over-voltage input and the non-inverting under-voltage input externallyconnected to the 2.5 V reference. T A = TJ.
