Overview
The TLV3502AIDCNRG4 is a high-speed, dual-channel rail-to-rail comparator produced by Texas Instruments. This component is part of the TLV350x family, known for its fast 4.5-ns propagation delay and operation over a supply voltage range of 2.7 V to 5.5 V. The TLV3502 is particularly suited for low-voltage applications due to its beyond-the-rails input common-mode range and rail-to-rail output, which can directly drive either CMOS or TTL logic. The device is available in microsize packages, including 8-pin SOT-23 and 8-pin SOIC, making it ideal for portable and space-restricted applications.
