Product details

Quad 2-input OR gate in 14-SOIC — 74HC logic on a 2V–6V rail

The Texas Instruments SN74HC32DR is a quad 2-input OR gate from the 74HC family, packaged in a 14-SOIC (3.90 mm width) for surface-mount assembly. It operates across a 2V to 6V supply range.

No NRND or EOL notice; it remains a standard-catalog item for new designs. The ROHS3 status covers the EU RoHS exemption list — no restricted substances above the threshold.

Sourcing and supply

For volume BOM lines, the active lifecycle means no last-time-buy pressure — standard procurement cycles apply.

Frequently asked questions

Is SN74HC32DR RoHS compliant?

Yes, it is ROHS3 Compliant per TI's lifecycle data.

What is the difference between SN74HC32DR and SN74HC32N?

The SN74HC32DR is in a 14-SOIC surface-mount package (Tape & Reel / Cut Tape), while the SN74HC32N is in a 14-DIP through-hole package. The logic function, supply range, and temperature grade are identical.
