Power-Down, LVTTL/LVCMOS Input. Force high or leave open to power down input channel 1. Force
low to enable input channel 1. The MAX3845 powers down if both PWRDWN_1 and PWRDWN_2 are
forced high or left open.
Positive Power-Supply Connection. Powers the temp-sense circuitry.
LOS MUTE Enable Input. Connect to V
MUTE function.
Junction Temperature Sensor. Attach a ground-referenced voltage DMM to this pin to measure the
die’s junction temperature (see the V
Power-Down, LVTTL/LVCMOS Input. Force high or leave open to power down input channel 2. Force
low to enable input channel 2. The MAX3845 powers down if both PWRDWN_1 and PWRDWN_2 are
forced high or left open.
Positive Power-Supply Connection. Powers input channel 2 and output channels 3 and 4.
