TLV3214PWR

TLV321x and TLV322x are a family of 5V single-channel, dual-channel, and quad-channel high-speed comparators, available with push-pull or open-drain output options. This family offers an excellent speed-power combination, featuring a 40ns propagation delay, a full supply voltage range of 1.8V to 5V, and a quiescent supply current of only 40μA per channel. These characteristics, combined with fast response time, rail-to-rail inputs, low offset voltage, and high output drive current, make this family ideal for current sensing, zero-crossing detection, and a wide variety of other speed-critical applications. The family also incorporates a power-on reset (POR) function that holds the output in a known state until the minimum supply voltage is reached, preventing output glitches during system power-up and power-down. The TLV321x features a push-pull output stage capable of sinking and sourcing large currents, enabling symmetrical rise and fall times and fast driving of capacitive loads such as MOSFET gates. The TLV322x features an open-drain output that can be pulled up to voltages below or above the supply voltage. These devices are designed for low-voltage logic level translation or wired-OR logic configurations. All devices are specified for operation over an extended temperature range of –40°C to 125°C.
