STMICROELECTRONICS TS391ILT Voltage Comparator

The TS391 is a low-power single voltage comparator designed for wide voltage operations from 2 V to 36 V or 1 V to 18 V with split supply capabilities. It features ultra-low supply current of 0.2 mA, low input bias current of 25 nA, and low offset voltage of 1 mV, making it ideal for battery-powered and portable applications. Its input common-mode voltage includes ground, and it provides TTL, DTL, ECL, and CMOS compatible outputs. The device operates at high speed with response times around 1.3 µs and supports various packages, including SOT23-5 and DFN8 2×2, suitable for compact designs and robust industrial use.
