Notes
1. This maximum value has an absolute maximum of 6.5 V independent of VDD.
2. The human body model ESD simulation is equivalent to discharging a 100 pF capacitor via a 1.5 kW resistor, which produces a single discharge transient. Reference "Philips Semiconductors Test Method UZW-BO/FQ-A302 (similar to MIL-STD 883C method 3015.7)".
3. The machine model ESD simulation is equivalent to discharging a 200 pF capacitor via a resistor and series inductor with effective dynamic values of 25 W and 2.5 mH, which produces a damped oscillating discharge. Reference "Philips Semiconductors Test Method UZW-BO/FQ-B302 (similar to EIAJ IC-121 Test Method 20 condition C)".




Description

The SAA5252 (LITOD) is a single-chip CMOS device, which will acquire, decode and display Line 21 Closed Captioning data from a 525-line composite video signal. Operation as an On-Screen Display (OSD) SAA5252 is also possible. Normal and line progressive scan modes are supported.
