Product details

Single inverting buffer in a tiny DSBGA — what you need to know

The SN74LVC1G240YZAR: The 32mA sink and source capability at each output is enough to drive a handful of CMOS inputs or a small LED directly.

The SN74LVC1G240YZAR is listed as obsolete. TI has ended production of this specific DSBGA variant.

Package and temperature — design-in notes

The part comes in a 5-DSBGA package measuring 1.4x0.9 mm (supplier device package 5-DSBGA). That is a tiny wafer-level chip-scale package with no leads — the solder balls are on the bottom, and there is no pin 1 mark you can see by eye under a magnifier. Orientation relies on the package outline and the ball map in the datasheet. Reworking this by hand is possible with a hot-air station and a steady hand, but the small ball pitch means lifting a pad is easy if the board is not preheated.

Frequently asked questions

Is SN74LVC1G240YZAR obsolete?

Yes, this part is obsolete. TI has discontinued production of the SN74LVC1G240YZAR. There is no official replacement order code from TI, so sourcing is through the surplus and broker channel.

What is the operating temperature of SN74LVC1G240YZAR?

This is the industrial temperature grade, suitable for most factory automation, telecom, and outdoor equipment.

What is the difference between SN74LVC1G240 and SN74LVC1G240YZAR?

The base part number SN74LVC1G240 refers to the same single inverting buffer function, but the YZAR suffix specifies the 5-DSBGA package and Tape & Reel packaging. Other suffixes (like DBVR for SOT-23 or DCKR for SC-70) indicate different package options. The electrical specifications — supply range, output drive, temperature range — are the same across the package variants.
