SN74AHC1G125DBVR is the TI AHC (Advanced High-Speed CMOS) single bus buffer gate in SOT-23-5 with the same pinout and 3-state output enable as NC7SZ125. AHC family operates at 2 V to 5.5 V VCC and provides higher output drive (±8 mA) than UHS NC7SZ. Same 3-state buffer function but functionally equivalent for applications where the higher drive is acceptable. Use as drop-in when design needs more output drive than the low-power NC7SZ can deliver.
