HT6222 General Description
The HT6221/HT6222 are CMOS LSI encoders designed for use in remote control systems. They are capable of encoding 16-bit address codes and 8-bit data codes. Each address/data input can be set to one of the two logic states, 0 and 1.
The HT6221/HT6222 contain 32 keys (K1~K32) and 64 keys (K1~K64), respectively. When one of the keys is triggered, the programmed address/data is transmitted together with the header bits via an IR (38kHz carrier) transmission medium.
HT6222 Maximum Ratings
Supply Voltage................................-0.3V to 6V
Input Voltage ................VSS-0.3V to VDD+0.3V
Storage Temperature................-50 to 125
Operating Temperature ..............-20 to 75
Note: These are stress ratings only. Stresses exceeding the range specified under "Absolute Maximum Ratings" may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.
