Description

This VLSI CMOS device is designed for switching

PCM-encoded voice or data, under microprocessor

control, in a modern digital exchange, PBX or Central

Office. It provides simultaneous connections for up to

256 64 kbit/s channels. Each of the eight serial inputs

and outputs consist of 32 64 kbit/s channels

multiplexed to form a 2048 kbit/s ST-BUS stream. In

addition, the MT89L80 provides microprocessor read

and write access to individual ST-BUS channels.
