UAF111

~AFlll ~AF311 FET INPUT VOLTAGE COMPARATORS FAIRCHILD LINEAR INTEGRATED CIRCUITS GENERAL DESCRIPTION - The IlAF111 and IlAF311 are monolithic, FET input Voltage Comparetors, constructed using the Fairchild Planar* epitaxial process. The ,uAF111 series operates from the single 5 V integraetd circuit logic supply to the standard ±15 V operational amplifier supplies. The .uAF111 series is intended for a wide range of applications including driving lamps or relays and switching voltages up to 50 Vat currents as high as 50 mAo The output stage is compatible with RTL, DTL, TTL and MOS logic. The input stage current can be raised to increase input slew rate.
