... The MAX976/MAX978/MAX998 dual/quad/single, high- speed, low-power comparators are optimized for +3V/+5V single-supply applications. They achieve a 20ns propagation delay while consuming only 225µA supply current per comparator. The MAX998 features a low-power shutdown mode that places the output in a high-impedance state and reduces supply current to 1nA. ...

... SYMBOL Wake-Up from Shutdown Power-Up Delay Note 1: The MAX998EUT specifications are 100% tested at T teed by design, not production tested. Note 2: Inferred from CMRR test. Either input can be driven to the absolute maximum limit without false output inversion, as long as the other input is within the common-mode voltage range. ...

... They achieve a 20ns propagation delay while consum- ing only 225µA of supply current per comparator. The MAX998 features a low-power shutdown mode that places the output in a high-impedance state and reduces supply current to 1nA. Activate shutdown mode by driving SHDN low. ...

... Shutdown Mode The MAX998 features a low-power shutdown mode, which is activated by forcing SHDN low. Shutdown mode reduces the supply current to 1nA (typical), dis- ables the comparator, and places the output in a high- impedance state ...

... V THR THF The Typical Operating Circuit shows an application using the MAX998 as an infrared receiver. The infrared photo- diode creates a current relative to the amount of infrared light present. This current creates a voltage across R When this voltage level crosses the voltage applied by the voltage divider to the inverting input, the output transitions. ...
