ICs for Cassette, Cassette Deck
AN6262N, AN6263N
1) When supply voltage is turned ON and Pin3 is set to “H”
(between the program detection ON), FF1-FF12 are reset and
FF13 is set, Switch SW
1
is all connected to a.
2) Mode is set (Pin7 “L”, Pin8 “H”).
3) SW
2
is connected to a.
4) Sound signal input to Pin1 becomes pulse after wave
shaped.
5) This sound pulse signal is input to the counter via
SW
1-2
.
6) Sound pulse signal is input to the counter by 3712
pulses, FF12 is inverted to “H” (
L H
). But no output is
obtained as the SW
1– 4
is connected to a.
7) Furthermore sound pulse signal is input by 256, FF12 in
inverted to “L” (
L
).
8) When FF12 is inverted from “H” to “L”, FF13 is inverted.
When FF13 is inverted, SW
1
is all connected to b.
9) Sound pulse signal, oscillation from oscillator and output of
FF12 are connected to reset pin of the counter, input of the
counter and output circuit, respectively.
10) Counter will count oscillation pulse signal and is reset by
the “H” of sound pulse signal (Program is there).
11) When sound pulse signal is stayed at “L” (program ends),
reset is released. Counter begins to count oscillation pulse
signal and FF12 is inverted to “H” by 3712 pulses.
When static capacitance of the external capacitor at Pin9 is
set to 0.1
μ
F, between the program is detected when no
signal time is more than 3 seconds.
12) Oscillation pulse signal is input furthermore by
256 pulses, FF12 is inverted (“H” “L”), FF13 is
also inverted and SW
1
is all connected to a.
13) Returns to 5) mode. Input pulse signal is counted by more
than 3712 + 256 pulses, program is recognized.

Between the program is detected by counting
oscillation pulse signal by 3712 pulses.
