Product details

Quad buffer with 3-state outputs for mixed-voltage buses

The Texas Instruments SN74LV126ADBR is a 74LV-series quad buffer with non-inverting logic and independent 3-state output enables. Each of the four elements drives 16 mA per channel, enough for moderate fan-out to CMOS or TTL loads without external line drivers.

No derating needed for the full range as long as the package's thermal limits are respected.

SSOP-14 footprint and tape-and-reel supply

The 14-SSOP body (5.30 mm wide, 0.209" pitch) is a standard JEDEC outline — the same footprint as a 14-pin TSSOP, so layout reuse across alternate logic families is straightforward.

ROHS3 compliant per, so it clears the EU RoHS exemption list without a waiver.

Frequently asked questions

Is SN74LV126ADBR equivalent to SN74LVC126ADBR?

Both are quad non-inverting buffers with 3-state outputs in the same 14-SSOP footprint, but the LVC variant (SN74LVC126ADBR) operates from 1.65V to 3.6V and typically offers higher drive current (24 mA). The LV part (this one) covers 2V to 5.5V, so the choice depends on your supply rail: use the LV for 5V buses, the LVC for sub-3V designs. They are not pin-compatible substitutes without checking the logic-family thresholds.

Can SN74LV126ADBR be used at 5V?

Yes. The supply range is 2V to 5.5V, so a 5V rail is within spec. At 5V the 16 mA output drive is maintained, and the 3-state outputs handle bus contention without damage as long as the absolute-maximum ratings are observed.
