H393P
LOW POWER LOW OFFSET VOLTAGE COMPARATORS
Description
The H393P series consists of two independent precision voltage
comparators designed specifically to operate from a single power supply
over a wide range of voltages, the input common mode voltage range
includes ground. Owing to adoption of clamp circuitry in input pins, mis-
operation is prevented by negative input.
