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.
Applications
Surveillance cameras and image input equipment
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.
• Inverter type driver: 1 channel
Input pulses are converted to VCCN and VEE1, VEE2
levels (inversion).
This circuit is an image sensor NSUB driver.
