Triple buffer for mixed-voltage and high-temp boards
The Texas Instruments SN74LVC3G34DCTR is a triple non-inverting buffer from the 74LVC logic family, each element handling one bit with push-pull outputs. It operates across a 1.65V to 5.5V supply range, making it a natural fit for bridging 1.8V, 2.5V, and 3.3V domains on the same board without external level shifters.
32 mA symmetric drive — what it means for fan-out
Each output can source or sink 32 mA, which is the figure to check when estimating how many CMOS inputs one buffer leg can drive. At 3.3 V, a typical 74LVC input draws under 5 µA, so the fan-out is limited by trace capacitance and edge rate, not DC current. The symmetric drive also means the rising and falling edges stay roughly matched, which simplifies timing closure on a shared bus.
Package and footprint: 8-LSSOP / 8-MSOP (SM8)
The SN74LVC3G34DCTR ships in the 8-lead SM8 package (2.80 mm body width), a compact footprint for space-constrained layouts. It is surface-mount only, so the reflow profile follows the standard LSSOP/MSOP guidelines. The supplier device package is SM8, which is the TI designation for this 8-pin shrink small-outline package.
No successor or second-source alternate is recorded in the official documentation.
