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.
FEATURES
• Wide operating voltage range V
CC = 8V~13.2V
APPLICATION
Driving of CCD image sensors in facsimiles, image scanners
and photocopiers
