description

The TC244 is a frame-transfer charge-coupled device (CCD) image sensor designed for use in single-chip color

NTSCTV 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 TC244 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 incorporated into 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 TC244 is achieved

by laminating a striped color filter with RGB organization on top of the image-sensing area. 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.
