/G3 HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD /G3 Rev: 2.3 2002-03-21/G3 INFRARED REMOTE CONTROL TRANSMITTER

DESCRIPTION

The SC50560 is a remote control transmitter utilizing CMOS technology housed in a 20-pin DIP or SO package. A 4x8 key matrix and extension bit inputs allow the transmission of up to 256 instructions. The transmission code consists of 16 bits code (8 bits custom code and 8 bits data code) and a leader code. Pin assignments and application circuit of SC50560 are optimized for easy PCB layout and cost saving advantage for remote control applications.

/G3 HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD /G3 Rev: 2.3 2002-03-21/G3 PCB WIRE LAYOUT SCHEMATIC: Transmitting tube output ground line The transmitting tube ground line and IC ground line should layout separated or overstriking ground line. The above IC only use to hint, not to specified. Note:/G2d6 * In wire layout, the power filter capacitor should near to IC. * In wire layout, should avoid power line and ground line too long. * Recommended infrared transmit unit and IC ground line should layout separated, or overstriking lines. * The emitter of triode connect 1 /Ga1 resistor at least. * Recommended triode use 9014.
