1.
Connect "OUT+" to "+12V" through a resistor (R
POL
) of 560 ohm 1/4 W (or another resistor
value that suits the circuit requirements).
2.
Connect "OUT-" to the TTL input.
3.
Pull-down "OUT-" with a resistor (R) of 180 ohm 1/8 W (or another resistor value that suits
the circuit requirements).
Static levels compatibility
The following table shows that the voltage levels are well compatible and that they remains
acceptable voltage margins for both TTL and LVTTL applications.
Voltage levels and margins, Rpol = 560 ohm 1/4 W, R = 180 ohm 1/8 W.
