Description

The M3004LAB1/M3004LDtransmitter IC are designed or infrared remote control systems. It has  total of 448 commands which are divided into 7 ub-system groups with 64 commands each. The ub-system code may be selected by a press button,  slider switch or hard wired.

The M3004LAB1/M3004LD generate the pattern or driving the output stage. These patterns are ulse distance coded. The pulses are infrared lashes or modulated. The transmission mode is efined in conjunction with the sub-system address. odulated pulses allow receivers with narrow- and preamplifiers for improved noise ejection to be used. Flashed pulses require a ide-band preamplifier within the receiver.
