4 / 15 page 12/9/04 Page 4 of 15 © 2003 Fairchild Semiconductor Corporation OPTICALLY ISOLATED ERROR AMPLIFIER FOD2741A FOD2741B FOD2741C Notes 1. Device is considered as a two terminal device: Pins 1,2 3 and 4 are shorted together and Pins 5,6,7 and 8 are shorted together. 2. Common mode transient immunity at output high is the maximum tolerable (positive) dVcm/dt on the leading edge of the com- mon mode impulse signal, Vcm, to assure that the output will remain high. Common mode transient immunity at output low is the maximum tolerable (negative) dVcm/dt on the trailing edge of the common pulse signal,Vcm, to assure that the output will remain low.
