Product Summary
The UPD3753CY is a 2088-bit high sensitivity CCD (Charge Coupled Device) linear image sensor which changes optical images to electrical signal. The UPD3753CY consists of 2088-bit photocell array and a line of 2088-bit CCD charge transferred register. It contains a reset a feed-through level clamp circuit, a pulse generator, and a voltage amplifier to provide high sensitivity and low noise. UPD3753CY also supports low power consumption with single 5 V power supply. The UPD3753CY can be driven by power supply and three input clocks owing to the built-in reset pulse generator and a clamp pulse generator.
