Overview
ICs for Cassette, Cassette Deck AN6262N, AN6263N Pause Detection Circuits of Radio Cassette, Cassette Deck s Overview The AN6262N and the AN6263N are the pause detection integrated circuits which select the program on the cassette tape.
In the ordinal method, tape speed is different depending on the PLAY and FF/REW, and also nonsignal time between the programs is different.
Therefore, two time constant circuit has been applied in order to detect each time.
The AN6262N and the AN6263N are proud of detecting the program by making the time corresponding to each non signal time logically in the one time constant circuit.
Furthermore, signal can be detected in this time constant circuit and beginning of the program is recognized when sound signal pulse increase more than specified numbers.

54 30 ˚ s Features • Built-in protection circuit to prevent mis-operation when power switch is turned ON.
Time-constant circuit for detection of no-signal period in PLAY and FF/REW.
• No-signal period and output pulse width can be selected by external capacitor.
• Detection level of input signal can be selected by external resistor.
• As the ON/OFF input for mode setting and pause detection, both TTL level and power source level can be used.
• Very few external components needed.
