description

The TC253SPD device is a frame-transfer, CCD image sensor designed for use in black and white NTSC TV,

computer, and special-purpose applications that require high sensitivity, low noise, and small size.

The TC253SPD sensor is a new device of the IMPACTRON

t family of very low noise, high sensitivity image

sensors that multiply charge directly in the 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 MOS device contains limited built-in gate protection. 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 VSS. Under no

circumstances should pin voltages exceed absolute maximum ratings. Avoid shorting OUT to VSS during operation to prevent

damage to the amplifier. The device can also be damaged if the output terminals are reverse-biased and an excessive current is

allowed to flow. 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.
