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: T_J = T_C = T_A
DC Electrical Specifications V_DD = 5V, T_A = 25°C, R_SET = 681kΩ, R_F = 22kΩ, R_LV = 82kΩ

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 10µA.
3. Tested for V_DD 5V ±5%.
4. Current sourced from pin 2 is V_REF/R_SET.

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