LVTTL/LVCMOS Compatible 3.3 V Optocouplers (1 Mb/s)
Data Sheet

RoHS 6 fully
compliant
RoHS 6 fully compliant options available;
-xxxE denotes a lead-free product
Description
These diode-transistor optocouplers use an insulating
layer between a LED and an integrated photodetector
to provide electrical insulation between input and out-
put. Separate connections for the photodiode bias and
output-transistor collector increase the speed up to a
hundred times that of a conventional photo-transistor
coupler by reducing the base-collector capacitance.
These optocouplers are available in an 8-pin DIP and in
an industry standard SO-8 package. The following is a
cross reference table listing the 8-pin DIP part number
and the electrically equivalent SO-8 part number.
The SO-8 does not require "through holes" in a PCB. This
package occupies approximately one-third the foot-
print area of the standard dual-in-line package. The lead
profile is designed to be compatible with standard sur-
face mount processes.
These optocouplers can be used in LVTTL/LVCMOS or
wide bandwidth analog applications.
The common mode transient immunity of 1000 V/µs
minimum to typical at VCM = 10 V guaranteed for these
optocouplers.
