TL331B-Q1中文资料汽车级 36V 单路比较器数据手册TI规格书

描述 Description

The TL331B-Q1 and TL391B-Q1 devices are the next generation versions of the industry-standard TL331-Q1 comparator. These next generation devices provide outstanding value for cost-sensitive applications, with features including lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, dedicated ESD protection cells with improved negative input voltage handling. The TL331B-Q1 can drop-in replace both the TL331-Q1 \"I\" and \"Q\" versions. The TL391B-Q1 provides an alternate pinout of the TL331B-Q1.

This device consists of a single voltage comparator designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible if the difference between the two supplies is 2 V to 36 V and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. To achieve wired-AND relationships, one can connect the output to other open-collector outputs.
