The Integrated Circuit MM74C922N CMOS provides the full encoder logical operation with an array of SPST switches. With this chip keyboard scan can be done and implemented with either external clock or with the external capacitive network element. The encoders are provided with on-chip full full pull-up devices which can switch 50k Ohms of resistance in the applications. The data of the circuit available goes out with a high-level valid keyboard entry.
The data available return with a high value in a key specification, this the two key roll-over switches in the power electronic system configuration. The internal registers allocate the memory location and provides for an easy expansion and bus operation LPTTL compatible working operation. The variable electronic specifications of the circuit provides good impedance and high resistive features for the thermal, maximum absolute temperature and variable junction temperature.
