The output can be placed in a high-impedance state via the output-enable pin, allowing multiple buffers to share a common bus line without contention. ## Wide temperature range and small footprint The SC-70-5 package (also known as SOT-353) occupies minimal board area, critical for dense PCB layouts in handheld or sensor-module designs. Standard lead times apply through authorized distribution. For dual-sourcing flexibility, the pin-compatible 74AHC1G125 (inverting version) shares the same footprint and supply range, though the output logic polarity differs.","metaTitle":"74AHC1G126DCKRG4 Buffer, Non-Inverting, 3-State, SC-70-5","metaDescription":"74AHC1G126DCKRG4 single buffer with 3-state output, 2V to 5.5V supply, -40°C to 125°C range.
