GENERAL DESCRIPTION

SM5172 is a remote control decoder paired

with SM5162 utilizing CMOS Technology. It

has 12-bit tri-state address pins providing a

maximum of 531,411 (or 312) address codes;

thereby, drastically reducing any code

collision and unauthorized code scanning

possibilities. SM5172 is available in several

options to suit every application needs :

variable number of data output pins, latch or

momentary output type.

FEATURES

* CMOS Technology

* Low power consumption

* Very high noise immunity

* Up to 12 tri-State code address pins

* Up to 6 data pins

* Wide range of operating voltage:

Vcc= 3 ~ 12 Volts

* Single resistor oscillator

* Latch or momentary output type

* Available in DIP and SOP package

APPLICATIONS

* Car security

* Garage door

* Home security/Automation system

* Toys

* Remote control for industrial use
