一華半導體股份有限公司 EN/DECODER MOSDESIGN SEMICONDUCTOR CORP. M3EB 3 STATES ENCODER 3 態編碼 IC 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 • 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 產品應用 • Car/home alarm system, garage control etc..
