The XL74C922 from Xinluda is a CMOS 16-key keyboard/keypad encoder, part of the industry-standard 74C922 family. It provides all of the logic needed to fully encode a 4×4 array of single-pole single-throw (SPST) switches, making it a drop-in solution for keypads, control panels, and human-machine interfaces. The “XL” prefix denotes the surface-mount SOP-20 version; the equivalent DIP-18 part is offered as the XD74C922.
The device performs the keyboard scan using either an external clock or a single external capacitor, and an internal debounce circuit requires only one additional capacitor. On-chip pull-up devices allow the use of switches with relatively high contact resistance, and the architecture requires no diodes in the switch array to eliminate ghost keys. A Data Available output flags valid key entries, simplifying interfacing to microcontrollers and digital logic.
The XL74C922 is a specialized keyboard-encoder IC with limited authorized-distributor availability, which can make it difficult to procure through standard channels. Pacific Component Xchange specializes in hard-to-find logic, interface, and discrete components like the XL74C922. We help engineering and procurement teams secure the parts that mainstream distributors no longer carry or never stocked.
Every order is backed by our commitment to authenticity and quality, with inspection and traceability to guard against counterfeit and substandard parts. We ship globally and can source by exact part number, package, and date-code requirements. Request a quote (RFQ) for the XL74C922 today and our sourcing specialists will respond with current availability, lead time, and pricing.
The XL74C922 is a Xinluda CMOS 16-key keyboard/keypad encoder in the 74C922 family. It fully encodes a 4x4 array of SPST switches and provides debounce, internal pull-ups, and a Data Available output, all in an SOP-20 surface-mount package.
They are the same 16-key encoder. The XL prefix designates the surface-mount SOP-20 package, while the XD prefix designates the through-hole DIP-18 package. Choose the one that matches your board layout.
Yes. The Xinluda XL74C922 is a functional equivalent within the industry-standard 74C922 16-key encoder family, sharing the same 3 V to 15 V supply range, debounce scheme, and Data Available output behavior. Always confirm pinout and package against your design before substitution.
The XL74C922 operates over a wide 3 V to 15 V supply range and an industrial operating temperature range of -40 u00b0C to +85 u00b0C, per the Xinluda datasheet.
The XL74C922 has little to no authorized-distributor stock, so pricing varies with availability. Pacific Component Xchange sources it on request. Submit an RFQ and we will provide current stock, lead time, and pricing.
No. The 74C922 architecture eliminates ghost switching without diodes in the switch array, and its on-chip pull-ups support switches with up to 50 ku03a9 ON resistance, simplifying keypad design.
