description
The TC253SPD-B0 is a frame-transfer, CCD image sensor designed for use in black and white, NTSC TV,
computer, and special-purpose applications requiring high sensitivity, low noise, and small size.
The TC253SPD-B0 is a new device of the IMPACTRON family of very-low noise, high sensitivity image sensors
that multiply charge directly in charge domain before conversion to voltage. The charge carrier multiplication
(CCM) is achieved by using a low-noise single-carrier, impact ionization process that occurs during repeated
carrier transfers through high-field regions. Applying multiplication pulses to specially designed gates activates
the CCM. The amount of multiplication is adjustable depending on the amplitude of the multiplication pulses. The
device function resembles the function of image intensifiers implemented in solid state.
This device contains circuits to protect its inputs and outputs against damage due to high static voltages or electrostatic fields. These
circuits have been qualified to protect this device against electrostatic discharges (ESD) of up to 2 kV according to MIL-STD-883C,
Method 3015; however, it is advised that precautions be taken to avoid application of any voltage higher than maximum-rated
voltages to these high-impedance circuits. During storage or handling, the device leads should be shorted together or the device
should be placed in conductive foam. In a circuit, unused inputs should always be connected to an appropriate logic-voltage level,
preferably either VCC or ground. Specific guidelines for handling devices of this type are contained in the publication Guidelines for
Handling Electrostatic-Discharge-Sensitive (ESDS) Devices and Assemblies available from Texas Instruments.
