HMHAA280 HMHA2801 HMHA281
DESCRIPTION
The HMHA 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 HMHAA 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.
