Additional preview pages of the HT6221 datasheet.

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.

Operating voltage: 1.8V~3.5V DOUT with 38kHz carrier for IR medium Low standby current Minimum transmission word: one word 455kHz ceramic resonator or crystal 16-bit address codes 8-bit data codes.
PPM code method Three double-active keys Maximum active keys - HT6221: 32 keys - HT6222: 64 keys Low power and high noise immunity CMOS technology.
