MC145483 Features

* high impedance. The device will operate normally when a logic 1 is applied to this pin. The device goes through a power

* up sequence when this pin is taken to a logic 1 state, which prevents the DT PCM output from going low impedance for at least two FST cycles. The VAG and VAG Ref circuits
