<P>PROBLEM TO BE SOLVED: To provide an interface circuit which can reduce noise. <P>SOLUTION: An interface circuit includes: a first buffer (111) which has a power supply voltage terminal connected to a first power supply voltage node and amplifies an input signal; a switch (124) connected between a second power supply voltage node and the power supply voltage terminal of the first buffer; and a first control circuit (127) which turns the switch from OFF to ON after delay time has been elapsed when the input signal of the first buffer rises from a low level to a high level. <P>COPYRIGHT: (C)2013,JPO&INPIT |
