Decoder With Data Output Pins

1. When the power is turned on ,the SC5272 activates the Stand-By Mode.

2. It then searches for signal. 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.

3. Whenever the address bits in frame match with that of the address configuration of the pin, the data bits are

stored into memory. Also, when this IC finds two continuous and identical data having the same address bits, the

data outputs is activated and the VT is enabled. The VT is disabled when there are two continuous mismatched

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