Texas Instruments TLV18xx/TLV18xx-Q1 Dual Micropower Comparators

Texas Instruments TLV18xx/TLV18xx-Q1 Dual Micropower Comparators are a series of 40V single, dual, and quad-channel comparators with multiple output options. The devices provide rail-to-rail inputs with push-pull or open-drain output versions. The TLV18xx/TLV18xx-Q1 have an ideal speed-to-power combination with a propagation delay of 420ns, a full supply voltage range of 2.4V to 40V, and a quiescent supply current of 5µA per channel.

The TI TLV18xx/TLV18xx-Q1 dual micropower comparators include Power-On Reset (POR) that ensures the output is in a known state until the minimum supply voltage has been reached before the output responds to the inputs. This POR prevents false outputs during system power-up and power-down.

The TLV181x/TLV181x-Q1 comparators offer a push-pull output stage capable of sinking and sourcing milliamps of current when controlling an LED or driving a capacitive load such as a MOSFET gate.

The TLV182x/TLV182x-Q1 comparators supply an open-drain output stage that can be pulled up to 40V independent of the comparator supply voltage.
