M3EB
GENERAL DESCRIPTION 功能叙述
The M3EB is a CMOS ASIC decoder. It will en-code 12 parallel input and serially transmit them to the output when D0 ~ D3
depressed. Paired with either M3D or M3DB. These address inputs are 3 states i.e. LOW(0)OPEN(X)HIGH(1).
FEATURES 产品特长
Built-in IR carriersuffix-I.
Up to 310 =59,049 codes, “0””X””1” Tri-states.
Single resistor oscillator.
Data transmit over 30 second auto power off.
2 or 4 direct date transmit ( internal pull-low resistor ).
M3EB-210 address2 data.
M3EB-48 address4 data.
APPLICATIONS 产品应用
Car/home alarm system, garage control etc..
