HCPL-253L-500E

These 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 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 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 designed 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 1000 V/µs minimum to typical at VCM = 10 V guaranteed for these optocouplers."
