Remote Control Encoder IC
PT2607
FUNCTION DESCRIPTION
OPERATION
Transmission is enabled by setting any one of the data pins -- D12 to D15 to “HIGH” (for PT2607
version) or by setting the TE (for PT2607B and PT2607C versions).
For PT2607 version, when transmission enable signals from Pins -- D12 to D15 -- are received,
PT2607 begins a three-word transmission cycle. This three-word transmission cycle will continue as
long as the transmission enable (D12 to D15) is held “HIGH”. When D12 to D15 goes to “LOW” (that is,
the transmission enable become “LOW”), the encoder output completes its final three-word
transmission cycle and then stops. Please refer to the diagram below.

For PT2607B & PT2607C versions, when transmission enable signals from TE is received,
PT2607B/PT2607C begins a three-word transmission cycle. This three-word transmission cycle will
continue as long as the transmission enable is held “HIGH”. When TE goes to “LOW” (that is, the
transmission enable become “LOW”), the encoder output completes its final three-word transmission
cycle and then stops. Please refer to the diagram below.
