The 16mA symmetric source and sink drive is typical for this logic family — enough to drive a few CMOS inputs or a short PCB trace without needing a separate line driver. The 14-SOIC package (0.209\", 5.30mm width) is a common footprint that routes easily on two-layer boards and reworks without hot-air stations. ## Supply voltage flexibility — 2V to 5.5V The 2V to 5.5V supply range is the headline selection parameter for this buffer. If your board has a 3.3V main rail and a 5V peripheral bus, this part bridges them without a level translator, as long as the input thresholds align. At 3.3V the 74LV family switches fast enough for most SPI and UART buses below 20 MHz; at 5V it meets TTL thresholds directly. The wide range also absorbs supply droop — a 3.3V rail that sags to 2.8V during a load transient still keeps the buffer operational. ## 3-state bus control Each of the four buffers has its own output-enable pin, so you can gate individual signals onto a shared bus without external AND-OR logic. The 3-state output goes high-impedance when the enable is low, letting another driver take the line. This is the standard architecture for address/data bus buffers in microcontroller memory expansion or for multiplexing sensor outputs onto a single ADC input channel.","metaTitle":"SN74LV126ANS 74LV Quad Buffer, Non-Inverting, 3-State","metaDescription":"Texas Instruments SN74LV126ANS quad buffer, non-inverting with 3-state outputs. 2V-5.5V supply, -40°C to 125°C, 16mA drive.
