TS3121AIYLT STMicroelectronics, Comparator, Open Drain O/P, 1.7 → 5.5 V 5-Pin SOT23-5

The STMicroelectronics single comparators offers high-speed response with low power consumption, making it ideal for industrial and automotive applications. Its fail safe circuit allows operation with biased input/output pins even when the supply is shut down, supporting energy saving designs. A guaranteed start up ensure stable output , while its compact size reduces PCB space and costs.

The comparator has a low offset voltage of 2 mV max at 25 °C in the A grade version
Features low power consumption with a typical value of 70 μA
The comparator operate within a wide supply voltage range of 1.7 to 5.5 V
Fast propagation delay of 60 ns
Fail safe architecture keeps the output in high impedance when VCC is 0 V
Supports an extended temperature range from -40 to + 125 °C
