EN/DECODER
M3EB
GENERAL DESCRIPTION
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
‧ Built-in IR carrier:suffix-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-2:10 address,2 data.
‧ M3EB-4:8 address,4 data.
APPLICATIONS
‧ Car/home alarm system, garage control etc.
