description

The TC244A is a frame-transfer charge-coupled device (CCD) image sensor designed for use in single-chip

color NTSC TV applications. The device is intended to replace the 1/2-inch vidicon tube in applications requiring

small size, high reliability, and low cost.

The image-sensing area of the TC244A is configured into 242 lines with 786 elements in each line. Twenty-nine

elements are provided in each line for dark reference. The blooming-protection feature of the sensor is based

on recombining excess charge with charge of opposite polarity in the substrate. This antiblooming is activated

by supplying clocking pulses to the antiblooming gate, which is an integral part of each image-sensing element.

The sensor is designed to operate in an interlace mode, electronically displacing the image-sensing elements

by one-half of a vertical line during the charge integration period in alternate fields, effectively increasing the

vertical resolution and minimizing aliasing. The single-chip color-sensing capability of the TC244A is achieved

by processing on striped-color filter with RGB organization. The stripes are precisely aligned to the sensing

elements, and the signal-charge columns are multiplexed during the readout into three separate registers with

three separate outputs corresponding to each individual color.

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 SUB. Under no

circumstances should pin voltages exceed absolute maximum ratings. Avoid shorting OUTn to ADB 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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
