TLV3601-Q1 and TLV3603-Q1 are 325 MHz, high speed comparators with rail-to-rail inuts and a propagation delay of 2.5 ns. The combination of fast response and wide operating voltage range make the comparators suitale for narrow signal pulse detection and data and clock recovery applictions in LIDAR, range finders, and line receivers.

The push-pull (single-ended ) outputs of the TLV3601-Q1 and TLV3603-Q1 simplify and save cost on board-to-board wiring for I/O interfaces while reducing power consumption when compared to alternative high-speed differential output comparators. They can directly interface most prevailing digital controllers and IO expanders in the downstream.

TLV3601-Q1 is available in tiny 5-pin SC70 package which makes it well suited for space constrained equipment. TLV3603-Q1 is packaged in a 6-pin SC70 package and maintains the same speed and size as TLV3601-Q1 while offering the additional features of adjustable hysteresis control and output latch capability.
