• Manufacturer Part Number: TEA0679
• Description: I2c-bus Controlled dual Dolby* B-type Noise Reduction Circuit for Playback Applications
• Manufacturer: NXP Semiconductors

Philips Semiconductors
I
The IC is capable of operating with I
below 5 V. This is achieved using the bus enable (pin 32) with different input voltages. An open pin or input voltages
above 5 V enable 5 V related I
I
below the specified LOW level.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
Notes
1. The TEA0679T allows a HIGH level at switching pins without voltage (V
2. Human body model (1.5 k ; 100 pF).
3. Machine model (0 ; 200 pF).
