MAX9107/MAX9108/MAX9109 25ns, Dual/Quad/Single, Low-Power, TTL Comparators are high-speed, low-power voltage comparators designed for use in systems powered from a single +5V supply. Their 25ns propagation delay (with 10mV input overdrive) is achieved with a power consumption of only 1.75mW per comparator. The wide input common-mode range extends from 200mV below ground to within 1.5V of the positive supply rail. The MAX9107/MAX9108/MAX9109 outputs are TTL-compatible, requiring no external pullup circuitry. These easy-to-use comparators incorporate internal hysteresis to ensure clean output switching even when the devices are driven by a slow-moving input signal. The MAX9107/MAX9108/MAX9109 are higher-speed, lower-power, lower-cost upgrades to industry-standard comparators MAX907/MAX908/MAX909. The MAX9109 features an output latch but does not have complementary outputs. The dual MAX9107 is available in both 8-pin SO and SOT23 packages. The quad MAX9108 is available in TSSOP and SO packages.
The MAX9107, MAX9108, and MAX9109 are high‑speed, low‑power voltage comparators designed for single‑supply operation at 5 V. They feature a 25 ns propagation delay, TTL‑compatible outputs, internal hysteresis, and a wide input common‑mode range.
