Active production, wide supply window
The SN74LVC3G34DCUT is an active-production Texas Instruments buffer from the 74LVC series, listed as current and ROHS3 compliant. It operates from a 1.65V to 5.5V supply, covering the standard 1.8V, 2.5V, 3.3V, and 5V logic rails without a separate level translator. Each of the three non-inverting buffers can source or sink 32mA of output current, enough to drive a standard CMOS input or a small LED directly. The push-pull output eliminates the need for an external pull-up resistor.
Package and temperature grade
Housed in an 8-VFSOP (0.091", 2.30mm width) package, the supplier device package is 8-VSSOP. The 0.50mm pitch and small footprint suit space-constrained PCBs, but the fine pitch demands careful solder-paste stencil design and a reflow profile that matches the lead-free assembly. Rated for -40°C to 125°C ambient, this part covers industrial and extended-temperature environments — motor drives, outdoor telecom, or under-hood automotive auxiliary circuits — though it lacks AEC-Q100 qualification, so it is not formally released for safety-critical automotive paths.
Sourcing and lifecycle reality
The 74LVC series is a mature, widely second-sourced logic family. No pin-compatible direct replacement from TI is listed, but the 74LVC3G34 function is generic enough that a parametric match from another vendor may exist — confirm the BOM position and the mating half before committing.
