Level shift circuit |
摘要 |
A level shift circuit shifting logic levels of an SCFL circuit to logic levels of a DCFL circuit, including an SCFL circuit having complementary outputs; two source follower circuits with their inputs respectively connected to the complementary outputs of the SCFL circuit; a high/low detecting circuit detecting "high" or "low" signals which have DCFL levels from the two source follower circuits and outputting signals having logic levels according to the detection results; and DCFL circuits with inputs connected to outputs of the high/low detecting circuit. Therefore, it is possible to obtain a level shift circuit operating with a wider voltage range and in a wider temperature range than the prior art circuit.
