Active quad buffer for mixed-voltage buses
The Nexperia 74LVC126ADB,112 is a quad non-inverting buffer with 3-state outputs from the 74LVC family, designed for mixed-voltage systems running from 1.2V up to 3.6V. Each of its four independent buffers sinks or sources 24mA, enough to drive typical logic buses or a row of LEDs without an external transistor. The 14-SSOP package (5.30mm body width) is a compact surface-mount footprint that reworks cleanly under hot air — the 0.65mm pitch is forgiving for hand rework if you keep the tip clean and use flux.
Supply flexibility and output drive
The 1.2V to 3.6V supply range lets this buffer bridge a 1.8V microcontroller to a 3.3V peripheral, or sit on a 2.5V backplane. The 3-state outputs go high-impedance when the output-enable pin is low, which is the standard way to share a data bus between multiple drivers. Symmetric 24mA drive at both logic levels means the rise and fall times match — important for signal integrity on short traces up to a few inches.
14-SSOP: rework-friendly footprint
The 14-SSOP (0.209", 5.30mm width) is a common narrow-body SSOP with 0.65mm lead pitch. The 1.75mm seated height keeps it low-profile for tight enclosures.
