The output can be placed into a high-impedance state, allowing multiple devices to share a common bus line without contention. No separate extended-temperature variant is needed for a motor drive or outdoor telecom panel. ## Output drive and 3-state control The 3-state output enable (OE) pin lets the designer float the output when the buffer is not actively driving the bus, preventing bus contention in multiplexed or shared-line architectures. This is a standard feature for address/data bus buffering or I/O expansion.","metaTitle":"74AHC1G126DBVTG4 Buffer, Non-Inverting, 3-State, SOT-23-5","metaDescription":"Texas Instruments 74AHC1G126DBVTG4 single buffer with 3-state output. 2V to 5.5V supply, -40°C to 125°C.

The 74AHC1G126 is the better fit for 5V-only or mixed 3.3V/5V designs where the wider voltage range and lower quiescent current of the AHC family are preferred.
