Overview
The LT1719CS6#TRMPBF is an UltraFast™ comparator from Analog Devices Inc., optimized for low voltage operation. This device is designed for high-speed applications and features internal hysteresis, making it suitable for use with slow-moving input signals. The comparator has rail-to-rail outputs that can directly interface with TTL and CMOS logic levels, and it also supports analog applications. It is available in a 6-lead plastic TSOT-23 package and operates over a temperature range of 0°C to 70°C.
