3 Description

The TLV360x are a family of 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 TLV360x

family 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

and SOT23 packages which makes it well suited

for space constrained equipment that benefit from

the comparators fast response time. 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. The TLV3602-Q1 is a dual

channel version of the TLV3601-Q1 and is packaged

in 8-pin VSSOP and WSON packages.

(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply

functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions.

If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully

functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

(2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.3 V beyond the supply rails must

be current-limited to 10 mA or less.

(3) Output terminals are diode-clamped to the power-supply rails. Output signals that can swing more than 0.3 V beyond the supply rails

must be current-limited to 50 mA or less.
