3 Description

The TLV3601 and TLV3603 are 325 MHz, high-speed

comparators with rail-to-rail inputs and a propagation

delay of 2.5 ns. The combination of fast response and

wide operating voltage range make the comparators

suitable for narrow signal pulse detection and data

and clock recovery applications in LIDAR, range

finders, and line receivers.

The push-pull (single-ended ) outputs of the TLV3601

and TLV3603 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 circuit.

The TLV3601 is available in tiny 5-pin SC70 package

which makes it well suited for space constrained

equipment. TLV3603 is packaged in a 6-pin SC70

package and maintains the same speed and size

as TLV3601 while offering the additional features

of adjustable hysteresis control and output latch

capability.
