An open collector compatible Loss of Signal is provided. The LOS must be pulled
high on the host board for proper operation. A logic “0” indicates that light has
been detected at the input to the receiver (see Section 2.5 Optical characteristics,
Loss of Signal Assert/Deassert Time on page 10). A logic “1” output indicates that
insuffi cient light has been detected for proper operation.
Power supply fi ltering is recommended for both the transmitter and receiver. Fil-
tering should be placed on the host assembly as close to the Vcc pins as possible
for optimal performance.
Recommended “Application Schematics” are shown in Figure 2 on page 5.
