continous 4)

1. All voltage values are measured with respect to the ground pin.

2. Pd has been calculated with Tamb = 25°C, Tjunction = 150°C.

3. TS487 stands 1.5KV on all pins except standby pin which stands 1KV.

4. Attention must be paid to continous power dissipation (VDD x 300mA). Exposure of the IC to a short circuit for an extended time period is

dramatically reducing product life expectancy.
