产品概述
描述
The TS3121 and the TS3121A single comparators permit high-speed response time at low power consumption over a supply voltage specified from 1.7 to 5.5 V. These devices operate over a wide temperature range from -40 °C to +125 °C making them ideal for industrial and automotive applications with the associated qualification.
Thanks to an embedded fail-safe circuit, the TS3121 and the TS3121A can operate with input/output pins biased while the supply pin is shut down to VCC = 0 V for energy saving applications. A guaranteed start-up time ensures a stable output condition after activating the supply rail.
Thanks to their small package size, the TS3121 and the TS3121A can be used in applications where space on the board is limited. It can thus reduce the overall cost of the PCB.
