Philips Semiconductors Product specification
CMOS digital decoding IC with RAM for
Compact Disc SAA7345
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
Notes
1. All VDD and VSS connections must be made externally to the same power supply.
2. Equivalent to discharging a 100 pF capacitor via a 1.5 kΩ series resistor with a rise time of 15 ns.
3. Equivalent to discharging a 200 pF capacitor via a 2.5 µH series inductor.
