NOTES:

* Same as HS 3120-2

1. The input coding is complementary binary if IO2 is used.

2. Digital input voltage must not exceed supply voltage or go below –0.5V . “ 0” <0.8V , 2.4V < “ 1” V DD

3. A ll strobes are level triggered. See TIM ING DIA GRA M .

4. Using the internal feedback resistor and an external opamp.

5. The output leakage current will create an offset voltage at the external opamps output. It doubles every 10ºC temperature increase.

6. Delay times are twice the amount shown at TA =+125ºC
