CMOS LSI
LC89901V
CMOS Driver IC for 1/5 and 1/6 Inch Image Sensors
Overview
The LC89901V is a high breakdown voltage CMOS vertical driver IC for 1/5 and 1/6 inch image sensors. Provision of a built-in level shifter means that an external clamp circuit is no longer required.
* Inverter type driver: 1 channel Input pulses are converted to VCCN and VEE1, VEE2 levels (inversion). This circuit is an image sensor NSUB driver.
Applications
Surveillance cameras and image input equipment
Package Dimensions
unit: mm 3175A-SSOP24
[LC89901V]
Functions
CMOS driver IC for 1/5 and 1/6 inch image sensors
Features
* CMOS process fabrication for low power dissipation * Built-in level shifter circuits to reduce the number of required peripheral circuits. * Miniature package (SSOP-24)
Structure
* Inverter type drivers: 8 channels Input pulses are converted to VCC1, VCC2 and VEE1, VEE2 levels (inversion). These are drivers for image sensor imaging and storage sections.
