一華半導體股份有限公司 EN/DECODER MOSDESIGN SEMICONDUCTOR CORP. M5E 3 STATES ENCODER 3 态编码 IC GENERAL DESCRIPTION 功能叙述 The M5E is a CMOS ASIC encoder. It will en-code 12 parallel data inputs (A0~A11) and serially transmit them to the output when transmits enable (TE) depressed. The address inputs are 3 states i.e. LOW (0) or OPEN (X) and HIGH (1). It will transmit 1 cycle each time TE depressed. FEATURES 产品特长 • Same Rosc matched to the DECODER M5D/F • 312 =531, 441 codes, “0”, “X”, “1” Tri-states • 4 cycles transmission each time • Direct data transmit type : (Elimination TE and diodes) ─M5E-H : switch to VDD • Built-in IR carrier : suffix –IR • DIP 18 or SO available APPLICATIONS 产品应用 • Car/home alarm system, garage control etc..
