Circuit Description
Trigger
Positive pulses on inputs E1 and/or E2 trigger the IC. The hold feedback in the logic has a delay of
several milliseconds. After this delay has elapsed, the tone sequence is started. This prevents
parasitic spikes from producing any effect on the trigger pins.
The following table shows the trigger options:
E1

Oscillator
This is a precision triangle oscillator with an external time constant (R x C). Capacitor
is charged by constant current to 1 V and then discharged to 0.5 V. The constant current is obtained
on pin
When the voltage on
complete tone sequence is issued. If the oscillator pin is short-circuited to GND during operation,
the sequence is repeated.
