MAX9201/MAX9202/MAX9203 high-speed, low-power, quad/dual/single comparators feature TTL logic outputs with active internal pullups. Fast propagation delay (7ns typ at 5mV overdrive) makes these devices ideal for fast A/D converters and sampling circuits, line receivers, V/F converters, and many other data-discrim- ination, signal restoration applications. All comparators can be powered from separate analog and digital power supplies or from a single combined supply voltage. The analog input common-mode range includes the negative rail, allowing ground sensing when powered from a single supply. The MAX9201/MAX9202/MAX9203 consume only 9mW per compara- tor when powered from a +5V supply. The MAX9202/MAX9203 feature output latches with TTL compatible inputs. The comparator output states are held when the latch inputs are driven low. The MAX9201 provides all the same features as the MAX9202/MAX9203 with the exception of the latches. The MAX9201/MAX9202/MAX9203 are lower power and lower cost upgrades to the MAX901/MAX902/MAX903 offering a 50% power savings and smaller packaging.
The MAX9201, MAX9202, and MAX9203 are high‑speed, low‑power voltage comparators offering TTL‑compatible outputs and optional latch functionality. They operate from separate analog and digital supplies or a single +5 V supply, with a typical propagation delay of 7 ns and a power consumption of only 9 mW per comparator.

| Typical propagation delay | 7 ns (typ at 5 mV overdrive) |
|---|---|
| Power consumption per comparator | 9 mW at +5 V supply |
| Analog supply voltage range | +5 V to +10 V (or ±5 V split) |
| Input voltage range | VEE‑0.3 V to VCC+0.3 V |
| Operating temperature range | -45 °C to +85 °C |
The typical propagation delay is 7 ns at a 5 mV overdrive.
Each comparator consumes about 9 mW at a +5 V supply.
Yes, both MAX9202 and MAX9203 have TTL‑compatible latch inputs that hold the output state when the latch input is driven low.
They can be powered from separate analog and digital supplies or from a single +5 V supply; analog supply can be +5 V to +10 V or split ±5 V.
