3 STATES ENCODER

3 态编码 IC EN/DECODER M5E 一華半導體股份有限公司 MOSDESIGN SEMICONDUCTOR CORP. GENERAL DESCRIPTION 功能叙述功能叙述功能叙述功能叙述 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 产品特长产品特长产品特长产品特长
