3.3V/5V Digital Optocoupler Family
The HCPL-253L diode-transistor optocouplers use an insulating layer between a LED and an integrated photodetector to provide electrical insulation between input and output. Separate connections for the photodiode bias and output-transistor collector increase the speed up to a hundred times that of a conventional phototransistor 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 footprint area of the standard dual-in-line package. The lead profile is desigened to be compatible with standard surface mount processes.
These optocouplers can be used in LVTTL/LVCMOS or wide bandwidth analog applications.
The common mode transient immunity of 15000 V/ms minimum at VCM = 1500 V guaranteed for these optocouplers.
