Abstract
The electronic circuit (100) of the invention receives first signals DATA (170) having logical '1' at high (VCCH) or low (VCCL) levels and logical '0' at reference level (ZERO) and generates second signals OUT (186) between high level (VCCH) and reference level (ZERO) without changing the information. The circuit comprises a first switch (161) and a second switch (161) serially coupled together to a common output node (103). The first switch (162) is controlled by a control signal (CTRL) derived from DATA, OUT, or optionally from a clock signal CLK. The first switch (161) is switched off before the second switch (162) is switched off. Contention (conducting at the same time) is thereby avoided and the first switch (161) and the second switch (162) can be implemented by substantially equal-sized components.
