MITSUBISHI MITSUBISHI 〈DIGITAL 〈DIGITAL ASSP〉 ASSP〉 M66700P/WP M66700P/WP DUAL HIGH-SPEED CLOCK DRIVER DUAL HIGH-SPEED CCDCCD 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 PIN CONFIGURATION (TOP VIEW) INPUT 1 NC INA→ 2 8 NC 7 → OUTA 3 6 VCC INB→ 4 5 → OUTB GND INPUT OUTPUT OUTPUT M66700P Outline 8P4 OUTPUT INPUT APPLICATION Driving of CCD image sensors in facsimiles, image scanners and photocopiers GND GND OUTA ← GND GND INA → GND GND 1 16 2 15 3 14 4 13 5 12 6 11 7 10 8 9 VCC GND →OUTB GND GND ←INB GND GND M66700WP Outline 16P4 OUTPUT INPUT NC: No Connection ABSOLUTE MAXIMUM RATINGS (Ta = 0 ~ 70°C unless otherwise noted) Symbol Parameter VCC VI VO Supply voltage Input voltage Output voltage Pd Power dissipation Tstg Storage temperature Conditions Ratings –0.5 ~ +15 –0.5 ~ +15 VCC Unit V V V 950 (P) /1800 (WP) mW –65 ~ 150 °C Output: “H” For single integrated circuit; Ta = 25°C (Note 1) Note 1: When Ta is 25°C or higher, conduct derating as follows: 7.7mW/C° (P) /14.4mW/°C (WP).
