The MM74C922N from Texas Instruments is a versatile 16-key encoder IC built using CMOS technology. It provides the necessary logic to encode an array of SPST switches, simplifying keyboard scanning implementations. The device can utilize 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.
Key features include on-chip debouncing circuitry that requires only a single external capacitor, which can be omitted if debouncing is not needed. It supports 2-key roll-over and has an internal register to remember the last key pressed. The 3-STATE outputs facilitate easy expansion and bus operation, and they are LPTTL compatible.
This encoder operates within a wide supply voltage range of 3V to 15V and has an operating temperature range of -40°C to +85°C. It is available in both 18-lead PDIP and 20-lead SOIC packages. The device is suitable for applications requiring efficient keyboard encoding and switch matrix scanning.
