Disable Input, CMOS/TTL. The data outputs are held static when this pin is asserted high.
The LOS function remains active when the outputs are disabled, CMOS. On the MAX3748,
this pin does not include ESD protection. If routed through the DS1858/DS1859 controller IC,
no additional ESD protection is required. On the MAX3748A, this pin has ESD protection.
Noninverted Loss-of-Signal Output. LOS is asserted high when the signal drops below the
assert threshold set by the TH input. The output is open collector (Figure 5). On the
MAX3748, this pin does not include ESD protection. If routed through the DS1858/DS1859
controller IC, no additional ESD protection is required. On the MAX3748A, this pin has ESD
protection.

amplifier and connect to V
Inverted Data Output, CML
Noninverted Data Output, CML
Received-Signal-Strength Indicator. This current output can be used to obtain a ground-
referenced voltage proportional to photodiode current with the MAX3744 by connecting an
external resistor between this pin and GND.
Output Supply Voltage. Connect to V
Offset Correction Loop Capacitor Connection. A capacitor connected between this pin and
CAZ1 extends the time constant of the offset correction loop. Typical value of C
The offset correction is disabled when the CAZ1 and CAZ2 pins are shorted together.
