PURPOSE: To provide a high-speed, reliable, and inexpensive bus receiver which detects transition of a low-voltage data signal especially in a circumstance of much noise. CONSTITUTION: The bus receiver 10 consists of differential input AMPs 18 and 18A, a pair of source followers 16 and 16A, and a detection AMP 12 having detection mode and latch mode. The bus receiver 10 is realized with a CMOS VLSI having plural FETs. The variance of the data signal of±0.2V to a reference signal is detected with respect to the data signal having a short setup time of about 1μS.
