The SN74AHC1G126DBVR with Buffers & Line Drivers Tri-State Single Bus from Texas Instruments is a single bus buffer and line driver with tri-state buffer output. It provides the flexibility of with a 3-state output, allowing it to be used as either a 1-to-1/2-to-1 or 1-to-1 multiplexer as needed. It has an operating voltage range from 1.65 V to 5.5 V and supports both high and low logic levels, making it ideal for 5 V and 3 V logic systems. The buffer also has an open-drain output with an output current of 12.5 mA per buffer. The chip is designed for multiple media, including LVDS, Fibre Channel, Gigabit Ethernet, ATM and SONET. Additionally, the chip is equipped with Schmitt-trigger inputs for increased noise immunity. The chip is designed with high level-shifting and bus buffering capabilities, making it a good choice for driving multiple buses in parallel.
