M3004LD REMOTE CONTROL TRANSMITTER

The M3004LAB1/M3004LD transmitter IC are designed for infrared remote control systems. It has a total of 448 commands which are divided into 7 sub-system groups with 64 commands each. The sub-system code may be selected by a press button, a slider switch or hard wired. The M3004LAB1/M3004LD generate the pattern for driving the output stage. These patterns ar.

Features

s are infrared flashes or modulated. The transmission mode is defined in conjunction with the sub-system address. Modulated pulses allow receivers with narrow-band preamplifiers for improved noise rejection to be used. Flashed pulses require a wide-band preamplifier within the receiver.
