HS9148 is infrared coding ASIC, which is manufactured by CMOS process. The chip has 18 functions and can transmit a total of 75 bar codes, of which 63 bar codes are sent continuously through the combination of keys, and 12 bar codes are single-transmitted codes (Pressing the key once only sends two frame code, if you still want to send codes, you must release the key and press it again).

◆ CMOS technology, low-power consumption, sleep current less than 0.6uA

◆ Fewer circuit components for external applications

◆ Multiple keys allowed

◆ Working voltage range: 2v~5v

◆ Different models can be used by adjusting the user code

◆ SOP16 Package
