(1.22) (0.71) $T2139 The QSA15X family are OPTOLOGIC ICs which feature a Schmitt trigger at output which provides hysteresis for noise immunity and pulse shaping. The basic building block of this IC consists of a photodiode, a linear amplifier, voltage regulator, Schmitt trigger and four output options. The TTL/LSTTL compatible output can drive up to ten TTL loads over supply currents from 4.5 to 16.0 volts. The monolithic die is packaged in a narrow angle, hermetically sealed, TO-18 metal can package. @ High noise immunity. = Direct TTL/LSTTL interface. @ Hermetically sealed package. m Reception angle of +12.
