In a circuit to convert a first logic signal having a first range to a second logic signal having a second range, a first metal oxide semiconductor (MOS) transistor selectively couples an output node to a first reference voltage when the output node is to be in a first state. A second MOS transistor has a source coupled to the output node and a gate coupled to a bias voltage. A current source circuit selectively biases the second MOS transistor to act as part of a source-follower circuit when the output node is to be in a second state. Additionally, a memory circuit has an input coupled to the output node, and an output. The memory circuit is configured to temporarily store a Boolean value of the output node when the output node transitions from the first state to the second state. Further, a discharging circuit is coupled to the output node and a second reference voltage. The discharging circuit is configured to temporarily provide a discharging path between the output node and the second reference voltage when the output node is transitioning from the first state to the second state. The discharging circuit has a first input coupled to the output of the memory circuit and a second input coupled to a control signal. The control signal indicates that the output node is to transition from the first state to the second state.
