Each channel can sink or source 32mA, enough to drive a small LED, a relay coil through a resistor, or a short unterminated trace. The output drive is symmetric, so rise and fall times stay balanced across the supply range. Housed in a 5-lead SC-70-5 (SOT-353) package, it takes minimal board area — useful for compact designs where every square millimetre counts. The 1.65V to 5.5V supply range means this buffer works on a 1.8V core rail, a 3.3V I/O rail, or a 5V legacy bus without a separate regulator. On a mixed-voltage board, one SN74LVC1G126DCKT can translate a 1.8V signal to a 3.3V output (or vice versa) as long as the input thresholds align — the 74LVC family's 5V-tolerant inputs accept up to 5.5V regardless of VCC, so a 3.3V output enable can control a 1.8V-powered buffer. No last-time-buy notice, no end-of-life risk on the horizon. This is a mainstream 74LVC part that TI continues to manufacture and support through both franchised and independent distribution. RoHS3 compliant. The SC-70-5 package is lead-free and compatible with standard reflow profiles. No special handling beyond the usual MSL precautions.","metaTitle":"SN74LVC1G126DCKT Buffer, Non-Inverting, 3-State, SC-70-5","metaDescription":"TI SN74LVC1G126DCKT single buffer with 3-state output, 1.65V-5.5V supply, 32mA drive, -40°C to 125°C.
