M1EN
GENERAL DESCRIPTION 功能叙述
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..
