M1EN

MOSDESIGN SEMICONDUCTOR CORP. 2 STATES ENCODER 2 IC EN/DECODER M1EN GENERAL DESCRIPTION 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 ‧ Same Rosc matched to the Decoder M1DA/FA. ‧ 212 = 4,096 codes. ‧ 4 cycles transmission each time. ‧ Direct data transmit type：(Eliminating TE and diodes). ─ M1EN-H：Switch to VDD. APPLICATIONS ‧ Car/home alarm system, garage control etc..
