Normally, after two matched code words (12-bit per word) transmitted from PT2248 is detected, the

latch strobe is generated, thereby producing a latch strobe pulse. This causes an “H” state output and

this output is sustained at “H” level as long as the continuous signal received. Approximately 160ms

after the key is released and the continuous signal is stopped, the output is reversed to “L” level by

above the last latch strobe pulse. Please refer to the diagram
