CS5212 is a remote control decoder circuit that works with CS5211. It has a maximum of 12 tri-state address pins and supports up to 531441 (or 312) addresses. It is very suitable for use in automotive safety systems, garage controls, remote control toys, remote control fans, industrial controls and home safety/automatic control.
The CS5212 is a CMOS‑based decoding integrated circuit designed to work with the CS5211. It offers up to 12 tri‑state pins and can handle up to 531 441 (or 32) different codes, reducing code conflicts and illegal scans. The device decodes RF or infrared signals, validates them twice, and outputs data pins while generating a VT pulse to indicate a valid code.
The document includes pin‑arrangement diagrams, pin descriptions, package options (18‑pin DIP, 20‑pin DIP, SOP), functional block diagrams, electrical parameters, and example application circuits for automotive safety, garage control, remote‑controlled toys, fans, industrial and home automation.
