HALF PITCH MINI-FLAT PACKAGE
4-PIN OPTOCOUPLERS
HMHAA280
DESCRIPTION
The HMHA281, HMHA2801 Series consists of a gallium arsenide infrared emitting diode driving a silicon
phototransistor in a compact 4-pin mini-flat package. The lead pitch is 1.27 mm.
The HMHAA280 series consists of two gallium arsenide infrared emitting diodes, connected in inverse
parallel, driving a single silicon phototransistor in a compact 4-pin mini-flat package. The lead pitch is 1.27mm.
