Applications Information
Power-Supply
Sequencing-Free Operation
Most CMOS switches require specific power-supply
sequencing in order to prevent device latchup. The
older DG417/DG418/DG419 devices require a proper
power-supply sequence of V+, V
L
, then V-. Otherwise,
it is necessary to add signal diodes to the circuit in
order to prevent potential latchups. The new
DG417L/DG418L/DG419L devices eliminate the need
for a V
L
input and allow any power-up sequence. Do
not exceed the absolute maximum ratings because
stresses beyond the listed ratings may cause perma-
nent damage to the devices.
