Quad 3-state buffer for mixed-voltage bus isolation
The SN74LVC126APWR is a Texas Instruments 74LVC-series quad non-inverting buffer with independent 3-state output enables. Each of the four elements drives up to 24 mA source or sink at the output, sufficient for fan-out to multiple CMOS or TTL loads on a shared bus. Supply voltage spans 1.65 V to 3.6 V, making it suitable for level translation between 1.8 V and 3.3 V domains without an external translator. The operating temperature range of -40°C to 125°C covers industrial and automotive ambient conditions.
14-TSSOP footprint and surface-mount integration
Housed in a 14-TSSOP package (4.40 mm width, 0.65 mm pin pitch), the SN74LVC126APWR mounts on standard surface-mount pads. The 14-TSSOP footprint is common across the 74LVC family, so a single PCB layout can accommodate multiple buffer or transceiver variants without board respin. Available in Tape & Reel (TR) or Cut Tape (CT) formats — the reel option suits automated pick-and-place for production volumes; cut tape works for prototype or low-quantity builds.
