Semiconductor integrated circuit device capable of outputting a plurality of interface levels |
摘要 |
A semiconductor integrated circuit device includes an interface corresponding to a relatively high signal level; an interface corresponding to a relatively low signal level; and an internal circuit made responsive to a signal through either interface for generating a signal to be transmitted to the other interface. The interface corresponding to a relatively high level, the internal circuit, and a drive control circuit constituting the input circuit and output circuit of the interface corresponding to a relatively low level are operated by an operating voltage corresponding to the relatively high level. An output element of the output circuit in the interface corresponding to a relatively low level, which is to be driven by the drive control circuit, is operated by an operating voltage corresponding to the relatively low level.
