CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests
are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA

NOTES:
1. No video signal, outputs unloaded.
2. At loss of signal (pin 10 high) the pull down current source switches to a value of 10A.
3. Tested for VDD 5V ±5%.
4. Current sourced from pin 2 is VREF/RSET.

NOTES:
1. Width is a function of RSET.
2. C/S, vertical, back porch and H are all active low, VOH = 0.8V; vertical is 3H lines wide of NTSC signal.
3. Attenuation is a function of RF. See filter typical characteristics.
4. Vertical pulse width in absence of serrations on input signal.
