ABSTRACT:
Arrangement for accepting an input signal in a first voltage range and producing an output signal in a second voltage range. A transition detection circuit (230) detects a transition from a high level to a low level of the input signal and a control circuit (245) operates a first FET to produce the low level of the output signal. A second FET is operated by the high level of the input signal to output the high level of the output signal.
