TLV3501AIDG4 (TEXAS INSTRUMENTS)

The TLV3501AIDG4 is a Rail-to-rail High Speed Comparator with push-pull outputs that features a fast 4.5ns propagation delay and operation from +2.7 to +5.5V. Beyond-the-rails input common-mode range makes it an ideal choice for low-voltage applications. The rail-to-rail output directly drives either CMOS or TTL logic. A shutdown pin allows the device to go into idle when it is not in use. When the shutdown pin is high, the device draws about 2µA and the output goes to high impedance. When the shutdown pin is low, the TLV3501 is active. It has a robust performance when used with a good layout. However, comparator inputs have little noise immunity within the range of specified offset voltage (±5mV). For slow moving or noisy input signals, the comparator output may display multiple switching as input signals move through the switching threshold.
