Figure 22: Switch-1 used together with a green LED in a 3.3V host system. The status of the signal can also be used as input to
a host controller. Notice the 1kOhm serial resistor.
Figure 23: Switch-1 used together with a green LED in a 5V host system. The status of the signal can also be used as input to a
host controller. Notice the 1kOhm serial resistor.
The buffer can be removed in a 3.3V system if no restore switch is required (see Figure 24).
In a 5V system the high state output from the module is not enough to turn off the LED, so a 74HCT08 buffer can be used to raise the
high level to 5V (see Figure 25).
The 74HCT08 gate is also available in a single gate package (74AHCT1G08).
