ELECTRICAL CHARACTERISTICS
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
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.
