NOTES:

1. All voltages are referenced with respect to ground.

2. Voltages across the potentiometer terminals (RL, RW, RH) cannot exceed VCC or go below ground by

0.5V.

3. Inputs UC and DC are internally pulled up with resistance of 100kΩ.

4. UC and DC inputs are internally pulled up to VCC via a 100kΩ resistor.

5. Active current is specified when the inputs UC or DC are active.

6. Standby current is the current consumed when the UC, DC, and STR inputs are inactive.

7. Input pulse width is the minimum time required for an input to cause an increment or decrement.

8. Repetitive pulse inputs on UC or DC will be recognized as long as they are within 500ms of each

other. Pulses occurring faster than 1 ms apart may not be recognized as individual and separate

pulses.

9. Input pulse timing has tolerances to ±10%.

10. Capacitance values apply at 25°C.

11. For VCC = 5V±10%, maximum VIL = +0.8V. Input logic levels are referenced to ground.

12. If not used STR should be connected to ground.

13. The DS1809 is offered in three values: 10kΩ, 50kΩ, and 100kΩ.
