description
The TL1593C is a three-channel sample-and-hold integrated circuit designed for use in processing video
signals generated by TI virtual-phase CCD image sensors. It can be used with one-, two-, and three-channel
color and monochrome TI virtual-phase CCDs.
Each sample-and-hold channel consists of a differential-input buffer, a digitally controlled switch, and an output
buffer that has high impedance. Separate supply and ground pins are provided for the analog and digital
sections to ensure optimum isolation. Internal-hold capacitors are included to reduce the external parts count.
The differential inputs allow the amplifier return pin of the imager to be connected to CIN of the sample-and-hold
circuit to obtain common-mode rejection for antiblooming clock transients in the CCD. The analog inputs should
be capacitively coupled from the CCD outputs to ensure optimum performance.
The TL1593C is supplied in a 16-pin plastic package and is characterized for operation from 0°C to 70°C.
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,

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 V
