M1EN-H

一華半導體股份有限公司 MOSDESIGN SEMICONDUCTOR CORP. EN/DECODER 2 STATES ENCODER 2 态编码 IC GENERAL DESCRIPTION 功 能叙述 M1EN The M1EN is a CMOS ASIC encoder. It will en-code 12 parallel inputs and serially transmit them to the output when transmits enable TE depressed. These address inputs are 2 states i.e. LOW (0) or OPEN (1). FEATURES 产 品特长 • Same Rosc matched to the Decoder M1D/F. • 212 = 4,096 codes. • 4 cycles transmission each time. • Direct data transmit type：(Eliminating TE and diodes). ─ M1EN-H：Switch to VDD. APPLICATIONS 产 品应用 • Car/home alarm system, garage control etc..
