DESCRIPTION
The 66124 optocoupler consists of two infrared LEDs optically coupled to two corresponding high gain darlington
detectors. This unique quad optocoupler provides high CTR and low leakage currents over the full military temperature
range (-55° to +125°C). The 66124 is a 20pin leadless chip carrier hermetically sealed package and is available in
standard and screened versions or tested to customer specifications. MIL-PRF-38534.
