It operates from a 2V to 5.5V supply, making it suitable for mixed-voltage systems where a 3.3V or 5V bus needs isolation or enable control. The output can be placed in a high-impedance state, allowing multiple drivers to share a common bus line. The 2V to 5.5V supply range covers 3.3V and 5V rails common in industrial and automotive electronics. At 2V it still switches, which matters for battery-powered or low-voltage core logic. Output drive is rated 8mA for both high and low states, enough to drive a single CMOS load or a short PCB trace. For longer lines or multiple loads, buffer fan-out should be checked against the input capacitance of the driven devices. ## Package and footprint — SC-70-5 Housed in a 5-lead SC-70-5 (SOT-353) package, this part occupies minimal board area. The pinout is standard for single-gate logic: ground, supply, input, output-enable (active-low), and data input.","metaTitle":"74AHC1G125DCKTG4 Buffer, Non-Inverting, 3-State, SC-70-5","metaDescription":"Texas Instruments 74AHC1G125DCKTG4 single-gate buffer with 3-state output, 2V to 5.5V supply, 8mA drive, -40°C to 125°C.
