Product details

Single-gate buffer with wide supply tolerance

It belongs to the 74LVC logic family and operates from 1.65 V to 5.5 V, making it suitable for mixed-voltage designs without needing a dedicated level translator. The 3-state output allows the buffer to be placed on a shared bus and disabled when another device drives the line.

SC-70-5: small footprint, rework-friendly

The SC-70-5 (SOT-353) package measures roughly 2.1 mm × 2.0 mm, a compact footprint for space-constrained boards. The leads are visible and accessible, so hand rework with a fine-tipped iron or hot air is straightforward — no hidden pads, no thermal pad to worry about.

Frequently asked questions

What is the difference between 74LVC1G126 and 74LVC1G125?

Both are single non-inverting buffers with 3-state outputs, but the 74LVC1G126 has an active-high output enable, while the 74LVC1G125 has an active-low output enable. The enable polarity is the only functional difference; they share the same supply range, drive strength, and package options.
