Overview
The TLV3404IPWR is a member of Texas Instruments' TLV340x family of nanopower comparators. This device is distinguished by its extremely low supply current of 470 nA per channel, making it ideal for battery-powered and wireless handset applications. The TLV3404IPWR operates over a wide supply voltage range from 2.5 V to 16 V and is specified for use in both commercial and industrial temperature ranges (0°C to +70°C and –40°C to +125°C, respectively). The device features an input common-mode range that exceeds the rails, from –0.1 V to VCC + 5 V, and includes reverse battery protection up to 18 V. This comparator is available in a 14-pin TSSOP package, among others, and is part of a family that includes single, dual, and quad versions in various packages.
