| A low-cost eight sound (five different sounds plus variations) generator IC with five LED indicators in a 16-pin DIL package. The sounds are selected by two push button switches either `serially' or `automatically'. The five LEDs will flash sequentially in synchronism with the five different sounds. The device can directly drive a small piezo sounder if required. Operating from a 2.2V to 5V DC power supply, the device has a typical stand-by current of just 1╡A at 3V, auto power-off and built-in oscillator. |
