Enable TTL Input. The laser output is enabled
only when EN is high and EN is low. If EN is
left unconnected, the laser is disabled.
Inverting Enable TTL Input. The laser output
is enabled only when EN is low or grounded
and EN is high. If EN is left unconnected, the
laser is disabled.
Power-On Reset Delay. To extend the delay
for the power-on reset circuit, connect a
capacitor to PORDLY. See the Design
Procedure section.
