What is the XL74LS20?

The XL74LS20 is a dual 4-input positive-NAND gate from Xinluda, part of the 74LS low-power Schottky TTL logic family. It contains two independent 4-input NAND gates in a single 14-pin SOP-14 package.

Is the XL74LS20 compatible with the standard 74LS20?

Yes. The XL74LS20 is functionally and pin-compatible with the industry-standard 74LS20 / SN74LS20 / DM74LS20, so it can typically be used as a drop-in replacement in existing designs.

What package does the XL74LS20 come in?

The XL74LS20 is supplied in a SOP-14 (14-lead small-outline) surface-mount package. Xinluda also offers a through-hole DIP-14 version under the part number XD74LS20.

What supply voltage does the XL74LS20 require?

As a 74LS TTL device, the XL74LS20 operates from a 4.75 V to 5.25 V supply, with 5.0 V nominal. For exact operating temperature range and full electrical ratings, refer to the Xinluda datasheet or contact Pacific Component Xchange.

Why is the XL74LS20 only available by RFQ?

The XL74LS20 is a specialty Xinluda part with limited authorized-distributor stock. Pacific Component Xchange sources it through its independent distribution network, so pricing and lead time are provided on a per-request basis. Submit an RFQ for current availability.

Can Pacific Component Xchange supply the XL74LS20 in production quantities?

Yes. Pacific Component Xchange handles both prototype and production volumes for hard-to-find and obsolete components. Contact us with your quantity and target date for a quote.

The XL74LS20 is a dual 4-input positive-NAND gate manufactured by Xinluda (Xinluda Information Technology Co., Ltd.) as part of its 74LS low-power Schottky (LS) TTL logic family. The device integrates two independent 4-input NAND gates on a single chip, each performing the logic NAND function on four inputs. It is a pin-compatible alternative to the industry-standard 74LS20 / SN74LS20 / DM74LS20, making it a practical drop-in option for legacy and cost-sensitive digital designs. The corresponding through-hole (DIP-14) version in the same Xinluda series is designated XD74LS20.
