ABSTRACT:
A monolithic optoelectronic integrated circuit having an optical emission portion (18) and a drive portion (11, or 22 and 21). The drive portion is capable of accepting TTL and standard CMOS logic voltage levels. In a first embodiment, the monolithic optoelectronic integrated circuit (10) has a light emitting diode (18) driven by a dual gate FET (11). In a second embodiment, the monolithic optoelectronic integrated circuit (20) has a light emitting diode (18) driven by two FETs (22 and 21). In each embodiment (10 or 20), a gate (13 or 23) of the respective drive circuit accepts the TTL or standard CMOS logic voltage. Further, in each embodiment current limiting is accomplished by coupling a gate with the source of the FET (11 or 22). Thus, the output of the light emitting diode (18, 18) is controlled by an input signal to the drive circuit.
