Overview
The TLV3501AIDBVR, produced by Texas Instruments, is a high-speed comparator that belongs to the TLV350x family. This device is characterized by its fast 4.5-ns propagation delay and rail-to-rail input/output capabilities. It operates over a supply voltage range of 2.7 V to 5.5 V, making it suitable for low-voltage applications. The TLV3501AIDBVR features a push-pull CMOS output stage and includes a shutdown function, which allows the device to enter an idle state when not in use. Available in microsize packages such as 6-pin SOT-23 and 8-pin SOIC, this comparator is ideal for portable and space-restricted applications.
