M1E

MOSDESIGN SEMICONDUCTOR CORP. 2 STATES ENCODER 2 IC EN/DECODER M1E GENERAL DESCRIPTION The M1E 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 2 states i.e. LOW (0) or OPEN (1). It will transmit 4 cycles each time TE depressed. FEATURES ‧ Same Rosc matched to the Decoder M1DA/FA. ‧ 212 =4,096 binary codes. ‧ 4 cycles transmission each time. ‧ DIP 18 or SOP or SSOP available. APPLICATIONS ‧ Car/home alarm system, garage control etc..
