    摘要： An oscillator circuit (OSC) incorporated in a semi­conductor integrated circuit and comprising an oscilla­tion input terminal (Xin), an oscillator output terminal (Xout), an inverting logic circuit (IV1), and a trans­mission gate (TR˝). The terminals (Zin) and (Zout) are connected to an external oscillator (X'tal). The inverting logic circuit (IV1) comprises an N-type MOS transistor (N2) and a P-type MOS transistor (P2). The input and output terminals of the logic circuit (IV1) are connected to the oscillation input and output termi­nals (Xin, Xout), respectively. The transmission gate comprises an N-type MOS transistor (N1˝) and a P-type MOS transistor (P1˝). Either MOS transistor has a source electrode and a drain electrode, one of which is connected to said oscillation input terminal (Xin), and the other of which is said oscillation output terminal (Xout). The gate-insulating film at least one of said MOS transistors incorporated in the transmission gate is thicker than those of other MOS transistors formed on the semiconductor substrate.
