Basic Circuitry

The integrated circuit T6801 requires a stabilized supply voltage (V

its electrical characteristics. An external buffer capacitor of C = 100 nF is recommended. An inte-

grated 14V Zener diode between V

The input stage is provided with an integrated 250 k

Ω pull-up resistor and can be directly con-

nected to a microcontroller. The output stage is an open collector, capable of sinking 20 mA.

Recommended external components:

• Pull-up resistor, R = 1 k

Ω

• Capacitor to GND, C = 470 pF, see Figure 4-1 on page 3
