Key Features
- 800 ps propagation delay enables high-frequency signal detection in optical receivers, clock recovery, and pulse-edge timing circuits
- LVDS differential outputs provide noise-immune, low-swing signaling compatible with high-speed digital interfaces and FPGA receivers
- Rail-to-rail input range allows comparison of signals spanning the full supply voltage without external level shifting
- Single-function 12-pin WQFN package with 5 µA bias current suits compact, high-speed comparator stages in mixed-signal designs
Applications
The TLV3605RVKT is designed for high-speed threshold detection applications including optical receiver discriminators, zero-crossing detectors in motor drives, and clock comparators in communications equipment where sub-nanosecond response time is essential. Its LVDS output is directly compatible with FPGA LVDS input banks, enabling seamless integration into data acquisition systems sampling at rates above 100 MHz. The rail-to-rail input capability and compact WQFN-12 package also suit pulse-width measurement circuits, window comparators, and line-receiver front-ends in industrial and test-and-measurement equipment.

Frequently Asked Questions
What makes the 800 ps propagation delay of the TLV3605RVKT suitable for high-speed optical receiver applications?
At 800 ps maximum propagation delay, the TLV3605RVKT can detect signal transitions at data rates exceeding 1 Gbit/s in optical receiver discriminator stages where the photodiode output must be converted to a clean digital pulse within less than one bit period. For a 100 Mbit/s link with a 10 ns bit period, the 800 ps delay consumes only 8% of the timing budget, leaving 92% for setup and hold margins at the downstream digital receiver. This performance far exceeds general-purpose comparators with typical delays of 50–100 ns.
How do the LVDS outputs of the TLV3605RVKT interface with FPGA high-speed inputs?
The TLV3605RVKT produces differential LVDS output signals with a common-mode voltage near 1.2 V and a differential swing of approximately 350 mV, which is directly compatible with LVDS-standard receiver inputs on Xilinx, Intel, and Lattice FPGAs. Connecting the positive and negative LVDS outputs to an FPGA's dedicated differential input pair requires only a 100-ohm termination resistor across the pair at the FPGA pin, allowing the comparator output to drive multi-meter PCB traces without signal integrity degradation at frequencies exceeding 200 MHz.
What is the input offset voltage of the TLV3605RVKT, and how does it affect threshold detection accuracy?
The TLV3605RVKT specifies a maximum input offset voltage of 5000 µV (5 mV). For a threshold set at 1.0 V, this offset means the actual switching point can vary between 0.995 V and 1.005 V across devices and temperature, which is acceptable in most digital threshold and zero-crossing detection applications. In precision window comparator designs where the switching threshold must be accurate to ±1 mV, a separate precision trimmer or a lower-offset comparator should be considered, or the TLV3605RVKT can be used in the high-speed outer-window stage paired with a slow precision comparator for the inner-limit check.
Over what temperature range does the TLV3605RVKT operate, and does the WQFN-12 package support automated SMT assembly?
The TLV3605RVKT is rated for industrial operation from -40°C to 125°C, covering the full industrial temperature range required for automotive-adjacent electronics, motor drives, and outdoor communication infrastructure. The 12-pin WQFN (WQCC-N12) package uses an exposed thermal pad that improves heat dissipation and is compatible with standard reflow soldering profiles per IPC-7711. The tape-and-reel packaging (RVKT suffix) supports pick-and-place assembly at high volume, and the RoHS-compliant Pb-free e4 finish meets global environmental regulations.
