Description

The TLV3604 and TLV3605 are 800-ps high speed comparators with a wide power supply range, rail-to-rail inputs, and a very high toggle frequency of 1.5 GHz. Along with an operating voltage range of 2.4 V to 5.5 V, all of these features come in industry-standard small packages, making this device an excellent choice for LIDAR, differential line receiver applications, and test and measurement systems.

The TLV3604 and TLV3605 both have very strong input overdrive performance of 450 ps, and narrow pulse width capabilities of just 600 ns. This combination of low variation in propagation delay due to input overdrive, and its ability to detect narrow pulses make these devices an excellent choice for Time-of-Flight (ToF) applications such as in factory automation and drone vision.

The Low-Voltage-Differential-Signal (LVDS) output of the TLV3604 and TLV3605 helps increase data throughput and optimizes power consumption. The complementary outputs helps to reduce EMI by suppressing common mode noise on each output. The LVDS output is designed to drive and interface directly with other devices that accept a standard LVDS input, such as most FPGAs and CPUs downstream in an application.

The TLV3604 is in a tiny 6 pin SC-70 package, which makes it easier for space sensitive applications such as an optical sensor module. The TLV3605 maintains the same performance as the TLV3604, and also offers adjustable hysteresis control, shutdown, and latching features in a 12 pin QFN package making it an excellent choice for test and measurement applications.
