Output drive is rated at 32 mA source and 64 mA sink per channel, enough to drive multiple CMOS or TTL loads without external buffers. The 2.7V to 3.6V supply range means this part works cleanly on a 3.3V rail with ±10% tolerance, and it will still function during brown-out conditions down to 2.7V. That's useful in battery-backed or lightly regulated supplies where the rail droops under load. The 32 mA high-level and 64 mA low-level output currents are asymmetric — the sink capability is double the source, so the part is better at pulling a line low than high. That matches the typical open-drain or wired-OR bus structure where the dominant state is low. ## Lifecycle and compliance No lead (Pb) exemption applies — the part is fully compliant for RoHS-sensitive builds.","metaTitle":"SN74LVTH126D 74LVTH Buffer, Non-Inverting, 3-State, 14-SOIC","metaDescription":"Texas Instruments SN74LVTH126D quad buffer with 3-state outputs, 2.7V–3.6V supply, 32/64mA drive, -40°C to 85°C.
