Remote Control Decoder IC

PT2294

DECODER WITH DATA OUTPUT PINS

1. When Power is turned ON, PT2294 activates the Stand-By Mode.

2. It then searches for signals. If there is no signal received, it remains in the Stand-By Mode;

otherwise, the address bits are compared with the address configuration of the pins.

Whenever the Address Bits in a Frame match with that of the Address Configuration of the Pin,

the data bits are stored into the memory. When the result is a match, it then undergoes another

matching (Address Bits in the Frame vs. Address Configuration of the Pin) and storing (data bits

stored in the memory) process.

When this IC finds two (2) continuous and identical data having the same address bits, the data

output(s) is activated and the VT is enabled. The VT is disabled when there are 2 continuous

mismatched addresses. For the momentary type, the data output is reset; while for the latch type,

the data output is sustained.
