14-SOIC hex buffer with open-drain outputs
The SN74LVC07ADT is a Texas Instruments 74LVC-series hex non-inverting buffer with open-drain outputs in a 14-SOIC package (3.90 mm width). It operates across a 1.65 V to 5.5 V supply range, making it suitable for mixed-voltage systems where a 3.3 V controller drives a 5 V peripheral bus. Each of the six buffers sinks up to 24 mA per channel with the open-drain output pulling to ground when active, and floating (high-impedance) when inactive. This allows wired-OR connections and level translation to higher voltages via an external pull-up resistor tied to the target rail.
Supply range and temperature grade
The 1.65 V to 5.5 V supply covers the full 1.8 V, 2.5 V, 3.3 V, and 5 V logic families. The -40°C to 125°C operating range qualifies it for industrial and automotive under-hood environments where the ambient temperature exceeds the commercial 85°C ceiling. The open-drain output structure means the high-level voltage is set by the pull-up resistor supply, not the buffer's VCC. This is the standard method for translating a 3.3 V logic signal to a 5 V TTL input without a dedicated level shifter IC.
Active production and sourcing posture
The SN74LVC07ADT is listed as Active in production with ROHS3 compliance. Sourced through independent distribution channels; availability and current pricing are confirmed at RFQ against the BOM quantity.
