All voltage values are measured with respect to the ground pin. 2. Pd has been calculated with Tamb = 25C, Tjunction = 150C. 3. TS487 stands 1.5KV on all pins except standby pin which stands 1KV. 4. Attention must be paid to continous power dissipation (V x 300mA). Exposure of the IC to a short circuit for an extended time period is DD dramatically reducing product life expectancy.
