FULL PITCH MINI-FLAT PACKAGE 4-PIN OPTOCOUPLERS HMA121 Series HMA124 HMA2701 Series HMAA2705 DESCRIPTION The HMA124, HMA121 series and HMA2701 series consists of a gallium arsenide infrared emitting diode driving a silicon phototransistor in a compact 4-pin mini-at package. The lead pitch is 2.54 mm. The HMAA2705 consists of two gallium arsenide infrared emitting diodes, connected in inverse parallel, driving a single silicon phototransistor in a compact 4-pin mini-at package. The lead pitch is 2.54mm.
