Connection Example 1: Line-driver Output
Applicable line driver: SN75174, manufactured by Texas Instruments
Inc., MC3487 or equivalent
Ω
Connection Example 2: Open-collector Output
Set limiting resistor R1 so that input current I falls within the following
range:
Ω
The examples below show how to select the pull-up resistor R1 so that
the input current I falls between 7 and 15mA.
Application Examples of V = IR
R1 = 1k Ω with V
CC
= 12V ±5% R1 = 180 Ω with V
CC
= 5V ±5%
Note: The following table shows the signal logic for an open-collector output.
Tr1 Output Level Signal Logic
ON Equivalent to high-level input
OFF Equivalent to low-level input
