| MITSUBISHI DIGITAL ASSP MITSUBISHI DIGITAL ASSP M66700P/WP M66700P/WP DUAL HIGH-SPEED CCD CLOCK DRIVER DUAL HIGH-SPEED CCD CLOCK DRIVER DESCRIPTION M66700 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. FEATURES * Output logic amplitude: 12V * High-speed rise/fall time tr = tf = 33ns (typical) CL = 1000pF * High output "H" level voltage: (VCC - 1) V minimum * Low output "L" level voltage: 0.5V maximum * TTL input level * Package with improved allowable power dissipation (WP) characteristic APPLICATION Driving of CCD image sensors in facsimiles, image scanners and photocopiers PIN CONFIGURATION (TOP VIEW) 1 NC INA 2 8 7 6 5 NC OUTA VCC OUTB OUTPUT OUTPUT INPUT INPUT GND 3 INB 4 M66700P Outline 8P4 GND GND OUTA GND GND INA GND GND 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 OUTPUT INPUT VCC GND OUTB GND GND INB GND GND OUTPUT INPUT M66700WP Outline 16P4 NC: No Connection ABSOLUTE MAXIMUM RATINGS (Ta = 0 ~ 70C unless otherwise noted) Symbol VCC VI VO Pd Tstg Supply voltage Input voltage Output voltage Power dissipation Storage temperature Parameter Conditions Ratings -0.5 ~ +15 -0.5 ~ +15 VCC 950 (P) /1800 (WP) -65 ~ 150 Unit V V V mW C Output: "H" For single integrated circuit; Ta = 25C (Note 1) Note 1: When Ta is 25C or higher, conduct derating as follows: 7.7mW/C (P) /14.4mW/C (WP).
