GENERAL DESCRIPTION 功能敘述
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 產品特長

• 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 產品應用
• Car/home alarm system, garage control etc..
