APPLICATION INFORMATION
OPERATING VOLTAGE
The THS7316 is designed to operate from 3-V to 5-V over a –40
°
C to 85
°
C temperature range. The impact on
performance over the entire temperature range is negligible due to the implementation of thin film resistors and
high quality – low temperature coefficient capacitors.
The power supply pins should have a 0.1-
μ
F to 0.01-
μ
F capacitor placed as close as possible to these pins.
Failure to do so may result in the THS7316 outputs ringing or have an oscillation. Additionally, a large capacitor,
such as 22
μ
F to 100
μ
F, should be placed on the power supply line to minimize interference with 50/60 Hz line
frequencies.
INPUT VOLTAGE
The THS7316 input range allows for an input signal range from –0.3 V to about (V
– 1.5 V). But, due to the
internal fixed gain of 2 V/V (6 dB) and the internal level shift of nominally 140-mV, the output is generally the
limiting factor for the allowable linear input range. For example, with a 5-V supply, the linear input range is from
–0.3 V to 3.5 V. However, due to the gain and level shift, the linear output range limits the allowable linear input
range to be from about –0.1 V to 2.3 V.
INPUT OVERVOLTAGE PROTECTION
The THS7316 is built using a high-speed complementary bipolar and CMOS process. The internal junction
breakdown voltages are low for these small geometry devices. These breakdowns are reflected in the

Maximum Ratings
table. All input and output device pins are protected with internal ESD protection diodes to the
power supplies, as shown in

THS7316
SLOS521–MARCH 2007
The THS7316 is targeted for standard definition video output buffer applications. Although it can be used for
numerous other applications, the needs and requirements of the video signal is an important design parameter
of the THS7316. Built on the Silicon Germanium (SiGe) BiCom-3 process, the THS7316 incorporates many
features not typically found in integrated video parts while consuming low power.
The THS7316 has the following features:
Single-Supply 3-V to 5-V operation with low total quiescent current of 18.3-mA at 3.3-V and 19.3-mA at 5-V.
Input configuration accepting DC + Level shift, AC Sync-Tip Clamp.
AC-Biasing is accomplished with the use of an external pull-up resistor to the positive power supply.
