SC73C1402
TYPICAL PCB WIRE LAYOUT SCHEMATIC:
Transmitting tube output ground line
The transmitting tube ground line and IC ground line should
layout separatedly or overstriking the ground line.
The above IC is only used to indicate the existence of it, not to specify.
Note:
* In wire layout, the power•filter•capacitor should be placed near to the IC.
* In wire layout, the user should avoid long power line and ground line.
* It is recommended infrared transmission unit and the IC ground line be laid out separately, or widening the
connection lines.
* The emitter of the triode should connect a 1¡ resistor at least.
* It is recommended to use the 9014 triode.
