MITSUBISHI 〈DIGITAL ASSP〉 MITSUBISHI 〈DIGITAL ASSP〉 M66701P M66701P DUAL HIGH-SPEED CLOCK DRIVER DUAL HIGH-SPEED CCDCCD CLOCK DRIVER DESCRIPTION M66701P Semiconductor Integrated Circuit is built in facsimiles and photocopiers to drive CCD linear image sensor data transfer clocks at high speeds. Because this IC takes in data on the TTL (transistor-transistor logic) level, it can be driven directly by a TTL integrated circuit.
