fter that, no signal time (more than 3 seconds) comes, between
the program is recognized and output pulse is generated.
If no signal time is less than 3 seconds, it is recognized not
between the program, but program.
Even if noise is contained before more than 3 seconds of 1st
music, between 1st music and 2nd music is detected.
When count of input pulse signal is by less than 3712, it is
recognized as no signal time. So noise is not recognized as
program. Detection of between noise and 1st music is never done.
(3) FF/REW
Mode is set (Pin7 “H”, Pin8 “L”). Switch S

is connected to
b.
No signal detection time (0.1 seconds) is only different,
count number and pulse width of the sound pulse signal,
which acknowledges program, are the same, and operation is
same, too.
(
4) Neither PLAY nor FF/REW
When Pin7, 8 are “H”, “H” and “L” and “L”, between the
program detection is not performed even if between the program
mode is ON.
(5) Switching case of PLAY FF/REW
Always reset and initialized.

Current driving capacitance of the output is minimum 100mA.
When relay is driven directly, equivalent load resistance is most
suitable at 200
. (AN6263N).
No signal detection time of PLAY, FF/REW and time of
output pulse width is determined by the relation between
oscillation cycle determined by the oscillation capacitance and
construction stage number of the flip-flop. When oscillation
period is t

Following items should be taken care in order to protect
destruction and keep reliability.
1. Please use it in the absolute maximum ratings. Take care
in case surge voltage shall be applied.
2. Pins except Pin5 should be used in the range of
positive voltage against Pin5.
3. Oscillation capacity should be used with superior thermal
characteristics.
4. When plunger and relay are connected to the output
circuit, diode should be connected to the both side of
coil in order to protect the IC against counter
electromotive force.
