TLV703x and TLV704x Small-Size, Nanopower, Low-Voltage Comparators 1 Features
The benefit of fast response time at nanoPower • Ultra-small X2SON, WSON, WQFN packages enables power-conscious systems to monitor and • Tiny SOT-23, SC70, VSSOP, and TSSOP respond quickly to fault conditions. With an operating packages voltage range of 1.6V to 6.5V, these comparators are • Wide supply voltage range of 1.6V to 6.5V compatible with 3V and 5V systems. • Quiescent supply current of 315nA The TLV703x and TLV704x also ensure no output • Low propagation delay of 3µs phase inversion with overdriven inputs and internal • Rail-to-rail common-mode input voltage hysteresis, so engineers can use this family of • Internal hysteresis comparators for precision voltage monitoring in harsh, • Push-pull output (TLV703x) noisy environments where slow-moving input signals • Open-drain output (TLV704x) must be converted into clean digital outputs. • No phase reversal for overdriven inputs • –40°C to 125°C Operating temperature The TLV703x has a push-pull output stage capable of sinking and sourcing milliamps of current when
