MM74C922WMX Description

Short technical summary and product information.

The MM74C922WMX from On Semiconductor is a CMOS key encoder IC that provides full logic for encoding an array of SPST switches. It supports an external clock or capacitor for keyboard scanning and includes on-chip pull-up devices, allowing for switches with up to 50 kΩ on resistance. This encoder features a 2-key roll-over capability and an internal debounce circuit that requires a single external capacitor.

 

The device has a Data Available output that signals a valid keyboard entry. The outputs are 3-STATE and LPTTL compatible, facilitating easy expansion and bus operation. The MM74C922WMX operates over a wide supply voltage range of 3V to 15V and consumes low power. It is supplied in a 20-SOIC surface mount package.

 

Key features include on-chip row pull-up devices, keybounce elimination with a single capacitor, and a last key register at the outputs. The encoder circuit is configured as 1 x 8:4, with one independent circuit. It is suitable for applications requiring keyboard encoding where space-saving and reliable switch input processing are essential.
