HT6222A Product details

General Description
The devices 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 HT6220A/HT6221A/HT6221B/HT6222A contain 30keys (K1~K20, K33~K34, K37~K38, K41~K42, K45~K46, K49~K50), 32 keys (K1~K32), 48 keys (K1~K32, K33~K34, K37~K38, K41~K42, K45~K46, K49~K50, K53~K54, K57~K58, K61~K62) and 64 keys (K1~K64), respectively. When one of the keys is triggered, the programmed address/data is transmitted to gether with the header bits via an IR (38kHz carrier) transmission medium.

Features
 Operating voltage: 2.0V~3.6V
 DOUT with 38kHz carrier for IR medium
 Low standby current
 Minimum transmission word: one word
 Build-in RC (Internal RC) oscillator
 16-bit address codes
 8-bit data codes
 PPM code method
 Three double-active keys
 Maximum active keys
   HT6220A: 30 keys
   HT6221A: 32 keys
   HT6221B: 48 keys
   HT6222A: 64 keys
