UM3758-108A/AM shape pin map UM3758-108A/AM encoding and decoding integrated circuit has the function of encoding sending and decoding receiving. The device itself has 10-bit three-state address inputs and 8-bit latch functions with a variety of ways to achieve long-distance remote control. It has the unique dual-duplex transceiver remote control and body functions. At present, this device is widely used in automotive, defense of the motherland, safe, mobile phones and military communications and other aspects of remote control, alarm, and password control circuits. Electrical parameters UM3758-108A/AM electrical parameters are identical. The main electrical parameters are: Working voltage range 3 ~ 12V, typical application voltage of 6V or 9V; Receiving input high minimum 4V, low maximum value of 2V; Other input level VIH = (VDD-0.5V ) ~ VDD, VIL = 0.5V; Output level VoH = (VDD-0.5V) ~ VDD, VOL = 0 ~ 1V; Data output current is ± 10mA (level is VDD / 2 时); TX / Rx-ended output current up-40mA or +20 mA; Chip operating clock oscillation frequency fosc = 160kHz.
