Product details

What this octal buffer does on the board

It operates from a 2.7V to 3.6V supply rail, making it a direct fit for 3.3V logic domains with tolerance for 2.7V battery-backed or low-voltage rails. Each output sinks or sources 24 mA symmetrical drive, enough to fan out to multiple CMOS loads or drive a handful of LED indicators without a separate transistor stage. The 3-state outputs let you share a data bus with other peripherals — pull OE low to enable, high to float the bus.

ROHS3 compliant per, so it passes EU material declarations without exemption paperwork.

Frequently asked questions

Does SN74LVCZ244APW have RoHS compliance?

Yes, it is ROHS3 compliant, covering all six restricted substances plus the four phthalates added under EU 2015/863.

What is the difference between SN74LVCZ244APW and SN74LVC244A?

The 'Z' in 74LVCZ denotes a higher-output-drive variant. The SN74LVCZ244APW delivers 24 mA per output, while the standard SN74LVC244A typically drives 12 mA or 24 mA depending on the specific sub-family — verify the exact 244A datasheet for its drive rating. Both are non-inverting octal buffers in 20-TSSOP with the same pinout, but the Z version is the one to pick when you need the full 24 mA symmetrical drive for bus fan-out or driving multiple loads.
