DESCRIPTION These devices consist of two independent precision voltage comparators, designedto operate with single or dual supplies. These differential comparators use the SGSTHOMSON silicon lin MOS process giving them an excellent consumption-speed ratio. These devices are ideally suited for low consumption applications.

All voltage values, except differential voltage, are with respect to network ground terminal. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. The magnitude of the input and + output voltages must never exceed the magnitude of the positive supply voltage. the Short circuit from outputs to VCC can cause excessive heating and eventual destruction.

Notes : 1. The specified offset voltage is the maximum value required to drive the output down to 400mV or up to 4V with RL = 100k to VCC+. 2. Maximum values including unavoidable inaccuracies of the industrial test. 3. The response time which is specified is the internal between the input signal and the instant when the output signal crosses 1.4V.
