NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

The IDT72V8980 is a ST-BUS® compatible digital switch controlled by a microprocessor. The IDT72V8980 can handle as many as 256, 64 Kbit/s input and output channels. Those 256 channels are divided into 8 serial inputs and outputs, each of which consists of 32 channels (64 Kbit/s per channel) to form a multiplexed 2.048 Mb/s stream.
