SGM8749 High-Speed Low-Power Comparator

The SGM8749 is a single high-speed comparator optimized for systems powered from a supply ranging from 2.7V to 5.5V. The device features high-speed response, low-power consumption, and rail-to-rail input range and open drain output. Propagation delay is 150ns, while supply current is only 22μA (Vs=3V).

The input common mode range of the SGM8749 extends beyond both power supply rails. The output pulls to within 0.1V of either supply rail without external pull-up circuitry, making the device ideal for interface with both CMOS and TTL logics. All input and output pins can tolerate a continuous short-circuit fault condition to either rail.

The SGM8749 is available in Green SOT-23-5 and SC70-5 packages. It is rated over the -40 to +85 temperature range.
