3 Description

The TLV3601-Q1 and TLV3603-Q1 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-

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 circuit.

The 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.
