What should engineers review before using XL74C923?

Review the 3 V to 15 V supply range, SOP-20 package footprint, 5-row/4-column matrix arrangement, open-drain column outputs, external oscillator timing capacitor, KBM debounce capacitor, and active-low Output Enable behavior.

What is the pinout of XL74C923?

Use the XL74C923 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about XL74C923 pinout to locate pins, power rails, and interface signals before layout.

AI summary

XL74C923 is a 20-key CMOS keyboard encoder for 5 × 4 SPST key matrices, supplied in SOP-20. It scans four columns, debounces key closures, latches a 5-bit key code, and asserts Data Available after valid detection.

Best for

5 × 4 switch matrices
low-part-count keypad interfaces
systems needing hardware debounce

Avoid if

A different matrix size is required
compliance documentation is mandatory but unavailable
a modern MCU-based keypad scan is preferred

Check before use

Confirm 5-bit output-code interpretation
Set scan and debounce timing with external capacitors
Verify output bus voltage compatibility and OE control
