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

DC Electrical Specifications

Unless otherwise state VDD = 5V, TA = 25°C, RSET = 680kΩ.

NOTES:

1. C/S, Vertical and Burst outputs are all active low - VOH = 2.4V, VOL = 0.8V.

2. Attenuation is a function of RSET (PIN6).

3. Typical min. is 0.3VP-P.

4. Refers to threshold level of sync. tip to back porch amplitude.
