Product details

The SN74LVC1G126YZAR: No LTB window remains; the part is available only from surplus or broker inventory.

The SN74LVC1G126YZAR is a single non-inverting buffer with a 3-state output, part of TI's 74LVC family. The output enable pin (active high) lets you float the output for shared bus applications.

Industrial temperature range and tiny DSBGA package

The package is a 5-bump DSBGA measuring 1.4 mm by 0.9 mm.

What the 32 mA output drive means for your design

That symmetry simplifies drive calculations for LED indicators or logic-level MOSFET gates.

Frequently asked questions

Is SN74LVC1G126YZAR obsolete?

Yes, Texas Instruments lists the SN74LVC1G126YZAR as obsolete. No further factory production is planned.

Does SN74LVC1G126YZAR support 3.3V?

Yes. The supply voltage range is 1.65 V to 5.5 V, so 3.3 V operation is well within spec. The 32 mA output drive at 3.3 V is typical for the 74LVC family.
