Description
The HMHA281, HMHA2801 Series consists of a gallium
arsenide infrared emitting diode driving a silicon pho-
totransistor in a compact 4-pin mini-flat package. The
lead pitch is 1.27mm.
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.
