What is the XL74LS27?

The XL74LS27 is a Xinluda triple 3-input positive-NOR gate logic IC from the 74LS27 family. It contains three independent 3-input NOR gates in a 14-pin surface-mount SOP-14 package, built on low-power Schottky TTL technology.

Is the XL74LS27 equivalent to the standard 74LS27?

Yes. The XL74LS27 follows the standard 74LS27 / 7427 triple 3-input NOR gate logic function and pinout. The 'XL' prefix is Xinluda's designation for the SOP-14 surface-mount version.

What package does the XL74LS27 come in?

The XL74LS27 is supplied in a SOP-14 (SOIC-14) surface-mount package. Xinluda also offers a through-hole DIP-14 variant under the part number XD74LS27.

What is the operating supply voltage of the XL74LS27?

The XL74LS27 operates from a 4.75 V to 5.25 V supply (5 V nominal), consistent with standard 74LS-series TTL logic.

Is the XL74LS27 in stock or available to order?

The XL74LS27 is a hard-to-find part with limited authorized-distributor availability. Pacific Component Xchange can source it - submit a Request for Quote (RFQ) and our team will provide availability, lead time, and pricing.

Can Pacific Component Xchange supply the DIP version (XD74LS27) as well?

Yes. While this listing covers the SOP-14 XL74LS27, our sourcing team can also help locate the pin-compatible DIP-14 XD74LS27. Include your preferred package in your RFQ.
