Built-in pull-down resistors mean LOW-level signals are obtained when inputs are open circuit. The resistance of the pull-down resistor varies with the applied voltage, as described in the Electrical Characteristics. LO LED drive output, HIGH level during non-play mode. BO Piezoelectric speaker driver output. LOW level output during non-play mode and during musical rest notes. HIGH level output during gaps between melody notes. VDD Supply. The rear surface of the chip is VDD level. VSS Ground T1, T2, TC Test inputs. Pull-down resistor built-in. TO Test output. The oscillator frequency (typ. 50kHz) is output for monitoring purposes. |
