Comparator Single ±15V/30V 8-Pin CDIP

The AS111 is a voltage comparator that has input currents nearly a thousand times lower than other similar devices like. It is also designed to operate over a wider range of supply voltages: from standard ±15V op amp supplies down to the single 5V supply used for IC logic. Their output is compatible with RTL, DTL and TTL as well as MOS circuits. Further, they can drive lamps or relays, switching voltages up to 50V at currents as high as 50 mA.Both the inputs and the outputs of the AS111 can be isolated from system ground, and the output can drive loads referred to ground, the positive supply or the negative supply. Offset balancing and strobe capability are provided and outputs can be wire OR’ed. Although slower than some devices (200 ns response time vs 40 ns), this device is also much less prone to spurious oscillations.
