Sixteen-way remote control circuit (T998C)

Relevant key device information applied in this article: T998C CD4514 9014 , as shown in the figure, is a sixteen-channel remote control circuit composed of a T998C-12V receiving module and a four-to-sixteen-channel decoder CD4514. This circuit can be used as either a latch output or a non-latch output, and SB is its control switch. When SB is connected to VDD, it is a latch output state, and the sixteen output terminals are not controlled by the Io output state; when SB is connected to the Io output terminal, it is a non-latched output state, and each output state is controlled by the Io output state. control. When using this sixteen-channel remote control receiving circuit, it must be encoded according to the binary-decimal coding method, and the operation of each channel must be performed according to the coding table. The remote control operation coding of each channel of the transmitter is as follows:
