| MOSDESIGN SEMICONDUCTOR CORP. EN/DECODER 3 STATES ENCODER 3 IC GENERAL DESCRIPTION M5E 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 * Same Rosc matched to the DECODER M5D/F * 312 =531, 441 codes, "0", "X", "1" Tri-states * 4 cycles transmission each time * Direct data transmit type : (Elimination TE and diodes) M5E-H : switch to VDD * Built-in IR carrier : suffix -IR * DIP 18 or SO available APPLICATIONS * Car/home alarm system, garage control etc.. BLOCK DIAGRAM X Oscillator Y Freq Divider Output Driver DO TE A0 Input Control Central Control Logic unit IR Carrier A11 *All specs and applications shown above subject to change without prior notice.
