TS3011IYCT: New small package for AEC-100 automotive applications

为了方便设计适用于空间有限型应用的系统,意法半导体畅销的比较器系列新增采用微型SC-70封装 (2.0 x 2.1 mm) 的 TS3011IYCT

Micropower comparators combining very low current consumption and outstanding robustness

TSX393TSX3702微功耗16 V双路CMOS电压比较器以及TSX339TSX3704
微功耗16 V四路CMOS电压比较器具有超低电流消耗,每个比较器的电流消耗仅为5 µA(典型值)。

此外,TSX比较器还有助于增强应用的可靠性和稳健性(能耐受4 kV HBM的ESD)。
