TLV3201AIDBVR

The TLV3201AIDBVR from Texas Instruments is a single-channel high-speed push-pull comparator that achieves an optimal balance of 40ns propagation delay and only 40μA supply current. The rail-to-rail input stage extends 200mV beyond both supply rails, enabling sensing at ground or supply level without additional level shifting. The push-pull output eliminates the need for an external pull-up resistor. Internal hysteresis ensures clean switching in noisy environments. The device operates from 2.7V to 5.5V across the -40°C to +125°C industrial temperature range, with a power-on-reset circuit that prevents false output transitions during power-up.

The TLV3201 uses a CMOS input stage that provides rail-to-rail common-mode range extending 200mV beyond either supply rail. The differential input pair feeds a high-gain comparator core that resolves small voltage differences within 40ns. Internal hysteresis (typically 3-5mV) prevents output chatter when the input signal crosses the threshold slowly or is noisy. The push-pull CMOS output stage actively drives both high and low levels without requiring an external pull-up resistor, providing faster transitions than open-drain comparators. The power-on-reset circuit holds the output low during initial power-up until the supply voltage reaches a valid level, preventing glitching.
