MN31121SA
CCD Image Sensor Vertical Driver IC
Overview
The MN31121SA is a 2D interline CCD image sensor vertical driver IC that integrates four vertical driver channels and one SUB drive channel on a single chip. This IC can reduce power consumption and the number of external parts. The MN31121SA consists of a vertical driver block that includes both level shifter circuits and 2-value and 3-value output driver circuits, and a SUB driver block that includes level shifter and 2-value output driver circuits.
Features
* Level shifter circuits Input (VDC, ground) output (VHH , VL) * 2-value output driver circuits (vertical driver block) Outputs: VM24 and VL * 3-value output driver circuits (vertical driver block) Outputs: VH, VM13, and VL * 2-value output driver circuits (SUB driver block) Outputs: VHH and VL

Usage Notes
1. If the SUB driver is not used: 1) Connect VHH (pin 20) to VH (pin 16). 2) Connect ISUB (pin 10) to VDC (pin 6). 3) Leave OSUB (pin 1) open. 2. Mount the bypass capacitors for power supply pins VHH (pin 20), VH (pin 16), VM13 (pin 4), VM24 (pin 19), VL (pin 2), and VDC (pin 6) as close as possible to the pin itself. 3. If the overcurrents that occur at power on and power off are limited to under 10 ms and under 100 mA, then the MN31121SA is guaranteed for 10,000 power cycle (power on/power off) operations. 4. Guarantee period after packing is opened The guarantee period after opening the moisture-proof packing is three weeks under environmental conditions of 30C and 70% RH. 5. The recommended reflow soldering temperature is 230C.
